This has come up so often that this should probably go into a coding styles FAQ (if its not already there).

More meat to mf's statement -- void main() *never was* C++; read this.

He was solving problems even after August at least, though. From little joey's stats: But seriously, send him an IM if you want.

I submitted a few problems in the last 5 days or so. I don't see them in the Author's Ranklist though. Basically, I see a difference in the number of Tries/Accpeted problems as found in the new web interface (for submission) and the Author's Ranklist. Am I missing something here?

What is wrong with this answer?

Nice example. When you come to think about it, assuming that the restrictions were on a per object basis, we wouldn't be able go beyond: ... // warning: not tested class foo { public: int doit(const foo *f) const { return x + f->x; ... The compiler would never ever compile this!

You have aptly demonstrated what Krzysztof claimed! Think of a problem where you have a class called Complex with two members of arithmetic type called real and img. Also, assume that an object of class Complex cannot access the private member(s) of another object of the same class. Can you still go...

Someone can take the hard disk out and copy all your data. Use disk

I was dumbstruck when I checked in on the board today to see a certain margaretkokgsmash on rampage. This has been going on for some time (not the same id, others maybe) ie. abuse of the board. We need to do something about this. And this brings to mind CAPTCHA. This would definitely put all members...

Q-Matrix. GIYF.

Fix the syntax errors first.
1. assign: function declaration/definition doesn't match.
check # of parameters in prototype declaration and usage.
2. C doesn't have references: so no *& stuff
3. abs is predefined in stdlib.h -- can't do that.

cout.precision/cout << fixed ... is giving you the CE. Exercise for the reader: find out which one and how to fix it Also, delete the other post.

0. Post in the right place. [Help On Languages -> C++] 1. What are you trying to do? Your code is declaring/defining an array of vectors (roughly a 2D array) of integers. Is that what you want? Or, is it that you want a 1D array in which case the following suffices: #include <vector> int main() { st...

[...]Confused... :-? it's just looping forever, isn't it? or anything else? I really don't understand... Don't miss the wood for the trees. The loop is not important in itself. Take out the `flush' from the cout statement and then try to run the program. Can you see any difference? Here's the relev...
