What will be the output of the following C++ code?

#include <iostream> 
#include <vector> 
 
using namespace std; 
 
int main() 
{ 
    vector<int> v; 
    for (int i = 1; i <= 5; i++) 
        v.push_back(i);
    cout<<v.capacity()<<endl;
    v.pop_back();
    v.pop_back();
    cout<<v.capacity()<<endl;
    return 0; 
}
