void main is incorrect: https://www.quantnet.com/threads/exercise-1.17500/#post-136644 . You should return 0; Regarding COFF: https://www.quantnet.com/threads/rebuild-failure.16392/#post-130513

What does the compile error say? You are missing a return statement.

That first popup is expected. You should click 'yes'. The second popup is telling you there was a compile error -- there is something incorrect with your code (you should click 'No' since there is no 'last one' yet). You should then check the build screen to see what the error is. You need to...

There is no reason you should not be able to get this to work :cool: Can you post a screenshot of the issue you see as well as the exact steps you are taking to load/run the code?

You cannot compile directly by opening .cpp files in vs. You must create projects and add the .cpp files into the project. You can then compile the project. Please see lecture 1 which details this process as well. If you are getting compile errors, then that means there is something incorrect...

Are you creating/opening projects or attempting to compile code files on their own?

I think this should be fine, but 6.0 is very outdated. What issue do you encounter with 2010?

Out of curiosity, from where did you download this (outdated) ExcelHelloWorld program?

Resubmissions, per the policy, are allowed until the next hw has been submitted. It is ok to take the quizzes regardless.

Yes, the course is fully self-paced within the 16-week allotted to earn the certificate. Length of study depends on how much time commitment you are able to put it. Some students (who were able to commit a large amount of their day to day) have completed the course is less than 20 days while...

VS is highly recommended. The best approach on mac would be to use a vm such as parallels. That being said, many students have used xcode and the like.

There is definitely some major differences between C# and C++ but there is no reason you should not be able to learn it pretty easily once you have a grounding in C++. I am a fan of Sams publishing (Teach Yourself C# in _ Days)

Does your Shape destructor have a body defined?

Are you sure it's not there but as a hidden file? Were you able to confirm manually? Keep in mind that that are likely in a different path on your machine than the one mentioned in the code. It is version specific

Once you submit your level 9 and complete quiz 10 your TA (myself) will contact you with details of the final exam; you can then arrange a mutually good date/time for the exam which may be shortly after your expiration date if necessary

Interaction on the forum is considered for bonus credit but is not essential for a good grade. More importantly, the forum is there for TAs to assist you in your learning experience. If you are confident enough that you can learn without that day to day assistance then it is not essential...

We TAs frequent the forums throughout the day to respond to any questions students may have on the material or the exercises. We also provide detailed feedback on each exercise for each hw submission.

Have you added it to the project? Simply having it open will not suffice. 1) Create an empty project 2) Add an existing or empty code file 3) Ensure that you have a main () 4) Compile

Sounds great to me. Would probably make sense between levels 3&4 as a supplement

What sort of message?

You can always private message your TA and he will respond relatively quickly. However, course policy encourages all material related questions to be posted on the forums.

Submissions are graded within 24-48hours. Often much quicker. Seldom a bit longer. Students post material questions on the forum where myself, assistant TAs, and other students frequent throughout every day. Therefore, you can generally expect rapid responses to your queries. Additionally...

The first 8 levels do not require any math beyond basic arithmetic/algebra. Level 9 is the application to fe. While it does utilize advanced math, it is structured so that one can successfully complete the exercises without fully understanding the math. This is because the primary focus is on...

There are no specific time limits per level, only for the course itself.

Pre-register just puts you into the list of prospective students. If you would like to actually enroll, see this: https://www.quantnet.com/threads/c-enrollment.13366/

I like Core Python Programming by Wesley Chun.

In what way do you expect to save on taxes, using an LLC?

I do not see any material benefit to doing that...What's your motivation?

The course is part of the Baruch pre-MFE program and the certificate is issued by Baruch College.

I concur with Andy and Dr. Duffy above. If you need to use Mac (which students have successfully used through level 8), students have used xcode. However, this is not recommended.

Think about it like this: A is the boss, C is your colleague, and 'you' are B. Mar 4, Mar 5, Mar 8 Jun 4, Jun 7 Sep 1, Sep 5 Dec 1, Dec 2, Dec 8 B said “I don’t know A’s birthday; C doesn’t know it either.” How can B know that C does not know it? In order for C to know it offhand, the day...

Many students have successfully used Mac for this course, until Level 9. I believe students have used xcode.

The course can be completed at each student's own pace. There is no requirement of finishing any chapter/level in a specific time period; however, there is a recommended pace (https://www.quantnet.com/posts/?post_id=90019) that students should adhere to in order to be able to complete the...

Hello world contains no logic, only IO. As soon as you introduce logic into your code, it can very easily fool you into thinking it is correct. Maybe your logic doesn't cover every path. Maybe it produces the correct output for the obvious case but not for a less obvious case

Dont use Latex for code. Use blocks (or the icon in the text box)

While I am sure that is a useful book, I highly doubt it would be of any use to the OP right now, who is looking to begin to learn programming

It's really a matter of opinion, but I like C++ How To Program By Deitel and also like the Sams publishing ('learn ... in 24 hours) books for quick learning. Obviously, tons of practice and attempting to code real, relevant projects is much more valuable than any book.

C/C++. It is much more difficult for a new programmer to move from Python (or even Java) to C/C++ than vice versa. Becoming knowledgeable and proficient in C/C++ will give you the tools you need to pick up other languages such as Python very easily and quickly. This is besides for the fact...

The course is fine for anybody new to the world of programming, so long as they are willing to put in the necessary time and effort.

You can approximate it using the CLT, probably in under a minute

Should be possible

Depending on the specific situation your TA will determine. Be sure to ask in the HW thread

I believe what you are saying is that congress only has the unlimited ability to borrow because of the existing mentality in the Fed of 'we can always print our way out of debt'; take that away and suddenly borrowing is not so innocuous anymore. While the Fed may have caused the borrowing...

That is true, but preventing the Fed from printing more money will not limit spending. Most of the spending is on 'borrowed' money (hence, the national debt) and not printed money. The problem is twofold: The Fed, and Congress's unlimited power to spend. Which is why we need a balanced...

I wonder if the hashes were really cracked. Check out this site: http://leakedin.org/ It supposedly lets you enter your password, converts it into the hash using the same scheme as LinkedIn, and checks if it is in the database of hacked passwords. My question is if this is a legitimate site, or...

As VBA speed is heavily dependent on many other variables, it is really not the best thing to compare system speeds with. Even if you used something such as C where you can control many of those variables, there are still others which cannot be controlled for. The OS itself, and how it manages...

You are right. For most conventional coding issues there should not be a need. I have encountered situations where perusing the assembly made debugging easier (may have been with C code though, not C++) -- I wish I had an anecdotal example offhand to debate upon, but I do not -- which...

However, knowing assembly will help one understand what is actually going on under the hood, which is useful in certain situations. In my experience, some elusive bugs in C++ code are easier found when stepping through the generated assembly and watching the registers/stack etc. -- maybe that's...

Interesting video. I must have seen 10 different reasons why Facebook didn't take off. The fact is that Facebook, as well as other social media are horribly overvalued. I had my short in at 44. To bad etrade doesn't allow shorts yet

ferdowsi, here is a simple thought experiment to assist you with this basic probabilistic concept: Say it is Tuesday, and the jackpot is at 460M. Say no one wins. Now, they base the next jackpot on projected ticket sales, and they for some reason only project a SINGLE ticket sale for Friday...

The lottery being a money maker for the state has no bearing on whether the EV is more than the price of the ticket and vice versa. Happens to be true that it's negative, but for other reason.

Not really, bc the last progression was from 290-363, which is ~150M tix sold. P(no winner) is about .42. The one before that, about .56, before that .64 and so on. It's not that far out. But it would be interesting to see what sort of RNG they are using.

Assuming 500M tickets sold: Odds of you being the only winner: 1/3,024,244,715

What are the odds of there being no winner? That would make next week very interesting...

Would be interesting to see the result if they hypothetically stopped selling tickets. How much you think a single ticket would go for?

Doesn't sound like a rational statement to me:alien: Superstition?

I thought this was going to be a thread about having a background with this: http://www-users.cs.umn.edu/~saad/spmath/

One can estimate the # of tickets sold by the jackpot size. I believe about .50 of each ticket sold goes into the jackpot. But you would need to calculate it based on the differential between last and current jackpot. I think the fact that the prize can be split (numerous) ways will drive...

This is the basis of misuse of many statistical 'studies'... The metric is helpful, just not to him as an individual.

Being a direct requirement or not in industry does not necessarily have bearing on whether a course should be in a curriculum. If knowing assembly will make you a better coder/debugger in other languages and gives you the necessary understanding of computer architecture, then it certainly should...

I am not sure what I said that implied that. Now that you mention it, that is definitely the case. Actuarial exams are arguably the most grueling set of exams for any field.

Some MFE's would make good actuaries (and vice versa), while many would not. Actuarial work is much less technical than Quant work, and some Quants are just not cut out for that. Hard to make a blatant generalization, but any MFE who has taken the CFA would probably have a relatively easy time...

Many of these companies hire actuaries to perform the duties you mentioned. Actuaries are somewhat better suited to deal with 'regular companies' than are MFEs, as many actuaries have the business/economics background in addition to a (bit weaker) quantitative background

MFE exam is definitely relevant to MFE. However, it is not theoretical in nature, and many MFE programs will require a theoretical grasp of those concepts.

While Exam P/1 is helpful, it does not concentrate whatsoever on theory (not measure theoretic). The Baruch classes are very theoretical.

Being Turing Complete does not say anything about ability of the language, in terms of possibilities. It only implies that any function can be calculated given input. There is actually quite a bit that can be done in C/C++ (mostly lower-level stuff) that would be virtually impossible to achieve...

Mostly unnecessary, but could come in handy if you have it already I guess. There is really no relation to the 2 fields, except for a few subtypes of corporate actuaries (such as DAC). Do not waste your time with anything other than basic accounting knowledge (income statements, balance...

Modeling derivatives is a foundation of more advanced actuarial modeling. Besides for the fact that insurance operates identically to an option mathematically...Actuarial science is a very broad field, borrowing much from mathematics, finance, and economics.

FE and accounting really do not have much intersection in regards to skill-set (although accountants would do better to understand quant). Most accountants that I know have starting salaries in the 50k range and work ridiculous hours. FE may have crazy hours as well, but salaries are...

I commute from Midwood to Baruch -- by car it can be more like 25 mins. Train is a pain because you have to transfer to the 6.

Most insurance companies have an 'actuarial development program' where they give you time off to study, pay for your exams, and give you raises/bonuses as you sludge your way through the exams. During that time (usually about 3-6 years if you go for FSA level) you rotate into different areas of...

This is true. However most people outside the actuarial realm will not have a clue as to what these examinations are.

Five actuarial exams are a lot to have prior to graduation. I assume you want to obtain your ASA? If you plan on becoming an actuary, it is very hard to get a job with an ASA straight out of college -- you will be overqualified. Most entry-level actuarial positions prefer somewhere in the 2-3...

You are taking that sentence out of context: -- "The right sort of person is so passionate about coding, they can’t be stopped from doing it. They typically started before high school — sometimes before middle school — and never looked back. They write everything from assembly to jQuery, on...

I believe Chris Ferguson would be a good counter example.

Do you have a link for a free version of this App? I can only find the full version in the Android market.

Will try to juggle beta testing with my heavy workload :cool:

No noticeable changes, at least for me, in the updated app.

I find printf easier for formatted output than cout. sprintf for formatting strings. Other C string operations, such as strcat etc. I use memcpy's often for lower-level stuff. But that's just personal preference. Agreed :)

Everyone has their own opinion on the matter, but I am of the school that one should learn C prior to learning C++. While C++ is a very powerful language, its core style really stems from C. Even now (for academic purposes), when I mostly use C++ (i.e. classes), I find it convenient to resort...

The browser works identical to a desktop browser -- clicking on a pdf in the browser downloads, and opens it in the Adobe Acrobat app. I assume this is the case for all Android phones. This is not that big an issue in my opinion, as I would be using the phone app for keeping up to date with a...

Here is the screenshot. This leads to another issue: links to forums open in the browser, not in the app. Had to find that manually.

Not a big deal - was only 1.99 :) Push is a great feature which seems to be working fine. The only two things that do not seem to be working are viewing/uploading attachments other than images, and attaching to a private message.

I actually have the full version. I downloaded it prior to reading your post on this thread-my browser popped an alert that the App was available so I decided to give it a try.

Here is a screenshot of latex. This reply was posted from my phone, so it will be a good test of the attachment capability.

Android app does not seem to support LaTex.

Good catch Amanda. Attachments are not showing up in the Android version as well ...

Downloaded the Android App (for HTC Evo). Up until now, I've been using Quantnet on my phone's browser. I have to say, the App makes things much easier to deal with. Have not encountered any issues yet! Will keep you posted.

Just add some code at the end of your main() that will wait for input, i.e. cin.get()

Many concepts in vector calculus are used in complex analysis -- which has interesting applications in solving differential equtions. So I can see that it can have its uses in the quant field, though not necessarily necessary. Some basic stuff is vital, such as gradients etc

GRE really depends on your background. With a relatively strong mathematics background, you should be able to ace the quant section with minimal to no study time. The verbal is harder to say; however, your score on the verbal sections are not nearly as important as quantitative.

That's correct (on average), although some can do it in 2-3 years. The associate level exams (P, FM, MFE, MLC, C) require a similar level of mathematics that a student finishing the first semester or two of Quant courses (at least based on Baruch's curriculum) will have (I have taken the...

City Hall is located at the origin, not the center of the city. An interesting twist on this problem would be to use a non-uniform distribution, though it would require a similar method to solve.

Yes, I mistyped, the city is 1 sq. mile, or 1-mile by 1-mile. 1/2 a mile is a good guess, but incorrect. The solution is a bit more complicated than that.

Just to clarify: I have not been accepted to both these programs yet. I am merely asking hypothetically, as I am going to be applying to both (of course I plan on being accepted to both as well :D). It will be helpful to know which program I "prefer" when applying.

A very interesting probability question: A city is 1-sq. mile by 1-sq. mile, with city hall at the origin. The odd thing about this city is that people can only walk in straight lines and no diagonals. If houses are uniformly distributed throughout the city, what is the expected walking...

That's on the right track. However, we need it to be 'arbitrarily large' -- we need some type of expandable container. The best way would be to create an object, with the different operations using operator overloading. That way it will actually operate as an int.
