make_pair (STL Samples) 

Illustrates how to use the make_pair Standard Template Library (STL) function in Visual C++.


template<class first, class second> inline
   pair<first,
      second> make_pair(
      const first& _X,
      const second& _Y
   )

NoteNote

The class/parameter names in the prototype do not match the version in the header file. Some have been modified to improve readability.

The make_pair STL function creates a pair structure that contains two data elements of any type.

// mkpair.cpp

// Functions: make_pair - creates an object pair containing two data
//                        elements of any type.

using namespace std;

/* STL pair data type containing int and float

typedef struct pair<int,float> PAIR_IF;

int main(void)
{
  PAIR_IF pair1=make_pair(18,3.14f);

  cout << pair1.first << "  " << pair1.second << endl;
  pair1.first=10;
  pair1.second=1.0f;
  cout << pair1.first << "  " << pair1.second << endl;
