Description:
This program swaps two numbers without using a temporary variable. It uses basic arithmetic operations to swap values, showcasing how arithmetic manipulation can be used to exchange values without needing extra memory.
Usage:
The user inputs two numbers, and the program swaps their values and displays the result.
Code:
C
#include <stdio.h>
int main() {
int a, b;
// Asking user to input two integers
printf("Enter two numbers: ");
scanf("%d %d", &a, &b);
// Swapping the numbers
a = a + b;
b = a - b;
a = a - b;
printf("After swapping: a = %d, b = %d\n", a, b);
return 0;
}
Explanation:
- Instead of using a temporary variable, the two numbers are swapped using arithmetic operations.
