back() vector c++ code example
Example 1: vector last c++
#include <iostream>
#include <vector>
int main ()
{
std::vector<int> myvector;
myvector.push_back(10);
while (myvector.back() != 0)
{
myvector.push_back ( myvector.back() -1 );
}
std::cout << "myvector contains:";
for (unsigned i=0; i<myvector.size() ; i++)
std::cout << ' ' << myvector[i];
std::cout << '\n';
return 0;
}
Example 2: c++ vector.back
#include <iostream>
#include <vector>
int main()
{
std::vector<int> myvector;
myvector.push_back(2);
std::cout << myvector.back() << std::endl;
myvector.push_back(46);
std::cout << myvector.back() << std::endl;
return 0;
}
