stl:utility:make_pair

Syntax:

  pair<TYPE1,TYPE2> make_pair( const TYPE1 &a, const TYPE2 &b );

The make_pair function returns a single object that contains the two items a and b. make_pair is a quick way of creating an instance of the pair class.

For example:

#include <string>
using std::string;
#include <iostream>
using std::cout;
#include <utility>
using std::pair;
using std::make_pair;
 
int main () {
  pair<int,string> tuple = make_pair( 42, "The answer" );
 
  cout << "tuple.first: " << tuple.first
       << ", tuple.second: " << tuple.second << '\n';
 
  return 0;
}
