Consider the following example:

int max(int x, int y)

                 {

                                return ( x > y) ? x : y ;

                 }

float max(float x, float y)

                 {

                                return ( x > y) ? x : y ;

                 }

 long max( long x,  long y)

                 {

                return ( x > y) ? x : y ;

                 }

char max(char x, char y)

                 {

                                return ( x > y) ? x : y ;

                 }

                void main()

                {

                  cout << max( 1,2) << endl;

                  cout << max( 4L,3L) << endl;

                  cout << max( 5.62,3.48) << endl;

                  cout << max('A','a') << endl;

                }

The output is :

                                                2

                                                4

                                                5.62

                                                a
