b = 10;
Welcome guys..
We will be write the program in c how to swap two number without using third variable.
Let's start the code..
#include <stdio.h>
int main()
{
int a, b;
printf("Enter the value of a : ");
scanf("%d", &a);
printf("Enter the value of b : ");
scanf("%d", &b);
a = a + b;
b = a - b;
a = a - b;
printf("The value of a is %d and b is %d", a, b);
return 0;

Output :
Enter the value of a : 10
Enter the value of b : 20
The value of a is 20 and b is 10
