vector::erase

[mickey0]

Hello
I have a vector and an index 'i';
I need something like:

for (int i = vec.size() - 1 ;i >= 0; i--) {
    if (something(i) ) vec.removeAt(i);
}
 

using c++ standard library; is it possibile from an int gets the iterator?

Thanks,

Nope.

You have to define a random access interator and set it.

vector<whatever>::iterator itr;
 
itr = vec.begin();
 
//then:
 
advance(itr);
 
//then
 
vec.erase(itr0;
