Removing elements from a vector

Demo Code

#include <cinttypes>
#include <iostream>
#include <vector>

using namespace std;

int main(int argc, char* argv[])
{
    vector<int32_t> stlVector {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16};

    cout << "The size is: " << stlVector.size() << endl;
    cout << "The capacity is: " << stlVector.capacity() << endl << endl;

    for (auto&& number : stlVector)
    {// w w w  .j  a  va 2  s  . c o m
        std::cout << number << ", ";
    }

    while (stlVector.size() > 0)
    {
        auto iterator = stlVector.end() - 1;
        stlVector.erase(iterator);
    }

    cout << endl << endl << "The size is: " << stlVector.size() << endl;
    cout << "The capacity is: " << stlVector.capacity() << endl << endl;

    for (auto&& number : stlVector)
    {
        std::cout << number << ", ";
    }

    std::cout << std::endl;

    return 0;
}
