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>

#include<conio.h>
void main( )
{
int a,b,c;
clrscr( );
printf("Enter A: ");
scanf("%d",&a);

printf("Enter B: ");
scanf("%d",&b);

c=a;
a=b;
b=c;

printf("\n The New Value Of A is : %d",a);
printf("\n The New Value Of B is : %d",b);


getch();
}
