How to prepare C++ questions?

[Andy Li]

I am a BS in math and now MFE student. I learn C++ by myself for much time, reading books like Primer. However, I still cannot handle C++ questions in interview. I was suggested to read "effective c++" or to practice more on previous interview questions, does that work?

Also, some interviewer just asked me about previous C++ project. As a student now, how can I get project experience of c++ programming?

Tks！！

Hi Andy, the best way to be good at C++ (or any other language) is to think about the project which would teach you a lot from the very beginning. Say, set an ambitious goal of writing one code per day. Start with mathematics, e.g. solving ax^2+bx+c=0 equation. Scan the books and Google for similar solutions. Compare what you wrote with other solutions. If you find some language structures that you don't know, study it, google it, try to include in your code and see the output. Modify, add new elements. Go through pain and hell of debugging.

After one week of doing so, keeping your pace, you will see how much you know. Don't jump in C++ topics too quickly. Set a timeframe for your progress. And stay motivated.

My tip would be: if you don't like C++, it terrifies you, make a hard effort of facing your fears. You will see after a while you start growing in C++ knowledge and self-confidence, and your fears start dying. Eventually, you will become addicted to that growth.

I'm folloing the same way right now with Python programming and share this experience at http://quantatrisk.com - Who knows, maybe one day you can be one of the best paid experts in C++?!!

Don't give up. Good luck!

The best way to learn C++ is by doing (programming a lot) C++. Start on a small project. That's _how_ you get experience (e.g. Monte Carlo, lattice, PDE, whatever, even a small analytic geometry application).

And get a feeling first for general Computer Science, e.g. variables, functions, memory, etc. etc.

To be honest with you, 'learning' C++ by memorising answers is pointless.

Thank you, Pawel!

I am keeping C++ coding everyday, and it does work!
It is helpful to compare my work with others, learning how to improve my coding skills.

Python is fancy. After more experience in C++ programming, I shall learn it by myself or in class later.

Thanks a lot!
I plan to read your book "Introduction to C++ for financial engineers" in the near future. I find in the book lots of great practical c++ projects of quant finance, they can help me learn by doing.
Memorizing answers is boring and useless. But maybe solving some interview questions as programming project is also helpful, isn't it?

Everything helps but I can imagine an interviewer might ask a question whose answer demands that you have written, compiled and run a C++ program.

I do agree with Daniel. Resistance against problems pays good dividends in time. Make sure you've invested in good stock. C++ is like GOOG. A growth option

Good idea.

If you are looking for c++ interview questions along with free online tests to practice,lets try with the link @ http://skillgun.com

I have been coding in C/C++ for +25 years. I am pretty sure that I would fail those interview questions linked previously.

what would it prove?

The typical C++ online exams are a joke.
