What happens when you attempt to compile and run the following code?#include <iostream>#include <map>using namespace std;int main() {int t[] = { 1, 1, 2, 2, 3, 3, 4, 4, 5, 5 };string s[] = { "one", "one", "two", "two", "three","three", "four", "four", "five", "five"}; map<int, string> m; for (int i = 0; i < 10; i++) { m.push_back(pair<int, string>(t, s));}for (map<int, string>::iterator i = m.begin(); i != m.end(); i++) { cout << i?>first << " ";}return 0;}
