#include <iostream>  
#include <map>

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

void printMap(const map<float, float>& mp)
{
	for (auto element : mp) {
		cout << element.first << ": " << element.second << endl;
	}
	cout << endl;
}

int main()
{
	map<float, float> mp = { { 1.1, 3.14 }, { 1.7, 3.87 }, { 1.2 , 2.25 }, { 1.8, 9.99 } };

	printMap(mp);

	return 0;
}

/*
run:

1.1: 3.14
1.2: 2.25
1.7: 3.87
1.8: 9.99

*/
