Two numbers are input through the keyboard into two locations C and D. Write a program to interchange the contents of C and D.

#include<stdio.h>
main ()

{
int A,C,D;
printf ("Enter the value of C and D: ");

scanf ("%d %d", &C, &D);

A=C;

C=D;
D=A;

printf ("\nThe exchanged values of C and D are: %d and %d ", C, D);

}
