Example: basic ex of maps in c++

#include <iterator>
#include <map>
using namespace std;
int main()
{
map<int, int> marks;
marks.insert(pair<int, int>(160, 42));
marks.insert(pair<int, int>(161, 30));
marks.insert(pair<int, int>(162, 40));
marks.insert(pair<int, int>(163, 50));
marks.insert(pair<int, int>(164, 31));
marks.insert(pair<int, int>(165, 12));
marks.insert(pair<int, int>(166, 34));
map<int, int>::iterator itr;
cout << "nThe map marks is : n";
cout << "ROLL NO.tMarksn";
for (itr = marks.begin(); itr != marks.end(); ++itr) {
cout << itr->first
<< "t t" << itr->second << 'n';
}
cout << endl;
return 0;
