C program for Swapping two numbers

 AIM:To write a program for swapping of two numbers.

ALGORITHM:

Step1: Start the program. 

Step2: Get the inputs a and b. 

Step3: Find a=a+b.

Step4: Find b=a-b. 

Step 5: Find a=a-b.

Step6: Print the result „a‟ and „b‟. 

Step7: Stop the program.

PROGRAM:

#include<stdio.h> 

void main()

{

int a,b; 

clrscr();

printf("Enter the values of a and b: "); 

scanf("%d%d",&a,&b);

a=a+b; 

b=a-b;

a=a-b;

printf("The values of a and b are: %d %d", a, b); 

}

Output

Enter the values of a and b: 10 20 

The values of a and b are: 20 10

RESULT:

Thus the C program to swap two numbers has been successfully executed and verified.
