Write program with overloaded prototypes of themax(), a function that displays maximum values of its arguments. Write three versions : one for single int value, one for two int values, and one for an array of int values.

/* Function Overloading :: All Function names are same but, arguments are of different types and different quantities */ 

#include<iostream.h>

#include<conio.h>

// Function 1

void themax(int a)

{

cout<< "\n The maximum number is = " << a;

}

// Function 2

int themax(int m, int n)

{

(m>n ? return m : return n);

}

// Function 3

int themax( int arr[ ])

{

int max = arr[0];

for(int i = 1; i < n ; i++)

{

if( max < arr[i] )

   max = arr[i];

}

return max;

}

void main()

{

int a[10], int x , y , max;

/* Function 1 calling ...demonstrated */

cout<< "\n Enter 2 numbers ";

cin >> x >> y;

if(x>y)

   themax(x);

else

   themax(y);

getch(); 

/* Function 2 calling ...demonstrated */

cout<< "\n Enter 2 numbers ";

cin >> x >> y;

max = themax(x,y);

cout<< The Maximum between " << x << " and " << y << " is " << max ;

getch();

clrscr();

/* Function 3 calling ...demonstrated */

for(int i = 0; i < 10 ; i ++)

{

cout<< "\n Enter an integer ";

cin >> a[i];

}

max = themax(a);                                   

cout<< "\n\n The maximum value is " << max ;

getch();

}
