## C Program To Swap Two Numbers

Swapping in C language can be done using various techniques, here in this swapping program we used two variables to perform swap two numbers.

### C Program To Swap Two Numbers Source Code

Copy paste the below source code in to c compilers and run the program to see the the result.

```/* Swapping Two Numbers Using Two Variables In C - SWAPTWONUMBERS.C */

#include<stdio.h>
#include<conio.h>
void main()
{
int num1, num2 ;
clrscr() ;
printf("Enter two numbers : ") ;
scanf("%d %d", &num1, &num2) ;
printf("\nBefore swapping : \n\n") ;
printf("num1= %d \t num2 = %d", num1, num2) ;

/* Swapping Two Numbers Logic */
num1 = num1 + num2 ;
num2 = num1 - num2 ;
num1 = num1 - num2 ;
printf("\n\nAfter swapping : \n\n") ;
printf("num1 = %d \t num2 = %d", num1, num2) ;
getch() ;
}```

#### C Program To Swap Two Numbers Output

After you compile and run the above program your C compiler asks you to enter two numbers, then it will show output before swapping and after swapping two numbers like below expected output.

Enter two numbers : 10 20

Before swapping :
num1 = 10 num2 = 20

After swapping :
num1 = 20 num2 = 10
