Pair in C++ Standard Template Library (STL)
In this tutorial, we will be discussing a program to understand pair in C++ Standard Template Library.
Pair is a container defined in the utility header that contains two values. It is used to combine two values and associate them even if they are of different types.
Example
#include <iostream>
#include <utility>
using namespace std;
int main(){
//initializing a pair
pair <int, char> PAIR1 ;
PAIR1.first = 100;
PAIR1.second = 'G' ;
cout << PAIR1.first << " " ;
cout << PAIR1.second << endl ;
return 0;
}Output
100 G
