Hi I have a program that deals alot with vectors and indexes of the elements of these vectors, and I was wondering:

  1. is there a difference between uint and unsigned int
  2. which is better to use one of the above types or just use int as I read some people say compiler does handle int values more efficiently, but if I used int I will have to check always for negative idxs which is pain.
  3. do you think iterators to be better? is it more efficient than normal indexing vectorx[idx]?

p.s the software will handle large data processes and good performance is a must have requirement

unsigned indexing iterator int c++

As other poster have noted, uint is probably a typedef for unsigned int If you're using Visual Studio, you can check that fact very quickly by pressing F12 while the text cursor is in uint to see its definition.
