Write a C Program to Swap two numbers without third variable.
#include<stdio.h>
int main()
{
int a,b;
printf(“Enter two numbers :\n”);
scanf(“%d %d”,&a,&b);
printf(“Before Swapping : a = %d, b = %d\n”,a,b);
a=a+b;
b=a-b;
a=a-b;
printf(“Before Swapping : a = %d, b = %d\n”,a,b);
return 0;
}
Output :
i) Enter two numbers :
65 9521
Before Swapping : a = 65, b = 9521
After Swapping : a = 9521, b = 65
