7.1.7.Definition of function template maximum

#include <iostream>

using std::cout;

using std::cin;

using std::endl;





template < class T >  

T maximum( T value1, T value2, T value3 )

{

   T maximumValue = value1; 



   if ( value2 > maximumValue )

      maximumValue = value2;



   if ( value3 > maximumValue )

      maximumValue = value3;



   return maximumValue;

}





int main()

{

   int int1, int2, int3;



   int1 = 1;

   int2 = 2;

   int3 = 3;



   cout << "\nThe maximum integer value is: " << maximum( int1, int2, int3 );

      



   double double1, double2, double3;



   double1 = 1.1;

   double2 = 2.2;

   double3 = 3.3;



   cout << "\nThe maximum double value is: "<< maximum( double1, double2, double3 );



   char char1, char2, char3;



   char1 = 'a';

   char2 = 'b';

   char3 = 'c';



   cout << "\nThe maximum character value is: "<< maximum( char1, char2, char3) << endl;

   return 0;

}

The maximum integer value is: 3
The maximum double value is: 3.3
The maximum character value is: c
