Method 1
#include <stdio.h>
int main()
{
int x = 10, y = 5;
// Code to swap 'x' and 'y'
x = x + y; // x now becomes 15
y = x - y; // y becomes 10
x = x - y; // x becomes 5
printf("After Swapping: x = %d, y = %d", x, y);
return 0;
}
Drawback – Doesn’t work if one of number is ‘0’
Method 2
#include <stdio.h>
int main()
{
int x = 10, y = 5;
// Code to swap 'x' and 'y'
x = x * y; // x now becomes 50
y = x / y; // y becomes 10
x = x / y; // x becomes 5
printf("After Swapping: x = %d, y = %d", x, y);
return 0;
}
Drawback – Doesn’t work if one of number is ‘0’
Method 3
#include <stdio.h>
int main()
{
int x = 10, y = 5;
// Code to swap 'x' (1010) and 'y' (0101)
x = x ^ y; // x now becomes 15 (1111)
y = x ^ y; // y becomes 10 (1010)
x = x ^ y; // x becomes 5 (0101)
printf("After Swapping: x = %d, y = %d", x, y);
return 0;
