}STL Signed/Unsigned mismatch

Say I'm trying to loop through an std::vector. I might have code like this:
When just looping those warnings are usually benign, but you should consider switching to a unsigned variable anyways. Alterantely, you can use iterators to loop through the vector.
Hello !
You can write
Or (simpler, since finnaly ti will resolve to the same thing)
The vector<>::size() methode returns an unsigned int (it makes not sense to return a signed one).
But unless you are dealing with very large vectors (more than 231 entries), your code will work correctly.

HTH,
