Simple Swapping C Program

Q. Write a simple program to insert two values through keyboard and interchange then values?

Example:if x=10

           y=20

        then after interchange

          x=20

          y=10

       

Ans.

#include<stdio.h>

#include<conio.h>

int main()

{

 int x,y,z;

 printf("Enter Values x and y : ");

 scnaf("%d%d",&x,&y);

 z=y;

 y=x;

 x=z;

 printf("\nValue of x=%d",x);

 printf("\nValue of y=%d",y);
 getch();
 return 0;

}

        Output of above program : 

Enter Values x and y : 25

35

Value of x= 35

Value of y= 25
