// This program illustrates how template functions can be overloaded.  
//
//	Key Points: 	1) Overloading template functions. 

#include <iostream.h>

// Free template function that expects two values of a given type and returns the
// summation of these two values.

template <class T>
T Add( T v1, T v2 )
{
 return v1 + v2;

}


// Free template functions that expects three values of a given type and returns the
// summation of these three values. Notice that this function is an overloaded 
// function. 

template <class T>
T Add( T v1, T v2, T v3 )
{
 return v1 + v2 + v3;

}



int main()
{
 int i1 = 3, i2 = 6, i3 = 12;
 double d1 = 2.5, d2 = 5.3, d3 = 9.6;

 cout << " The total of i1 and i2 is: " << Add( i1, i2 ) << endl << endl;
 cout << " The total of d1 and d2 is: " << Add( d1, d2 ) << endl << endl;
 cout << " The total of i1, i2 and i3 is: " << Add( i1, i2, i3 ) << endl << endl;
 cout << " The total of d1, d2 and d3 is: " << Add( d1, d2, d3 ) << endl << endl;

 return 0;
}

// The output of the program:
/*
 The total of i1 and i2 is: 9

 The total of d1 and d2 is: 7.8

 The total of i1, i2 and i3 is: 21

 The total of d1, d2 and d3 is: 17.4
