Ignore la capacité excédentaire.
void shrink_to_fit( );
Exemple
// vector_shrink_to_fit.cpp
// compile with: /EHsc
#include <vector>
#include <iostream>
int main( )
{
using namespace std;
vector <int> v1;
//vector <int>::iterator Iter;
v1.push_back(1);
cout << "Current capacity of v1 = "
<< v1.capacity() << endl;
v1.reserve(20);
cout << "Current capacity of v1 = "
<< v1.capacity() << endl;
v1.shrink_to_fit();
cout << "Current capacity of v1 = "
<< v1.capacity() << endl;
}
