How to print map using iterator in C++

Answer 1

#include <iostream>
#include <map>

using std::cout;
using std::endl;
using std::map;

int main()
{
	map<char, int> mp;

	for (int i = 0; i < 5; i++)
		mp.insert(std::pair<char, int>('a' + i, 97 + i));

	map<char, int>::iterator it;

	for (it = mp.begin(); it != mp.end(); it++) {
		cout << it->first << " = " << it->second << " ASCII " << endl;
	}

	return 0;
}

/*

b = 98 ASCII
c = 99 ASCII
d = 100 ASCII
