In C / C +Swap two variables in one line in

This is an example of swapping using C language

Example

#include <stdio.h>
int main() {
　　　int a =　28, b =　8;
　　　a　+= b　-= a = b　-　a;　//　method　1
　　　printf("After Swapping : %d\t%d", a, b);
　　　(a ^= b), (b ^= a), (a ^= b);　//　method　2
　　　printf("\nAfter Swapping again : %d\t%d", a, b);
　　　return 0;
}

Output Result

After Swapping :　828
After Swapping again :　288

In the above program, there are two variables a and b, which are assigned values separately28and8There are too many ways to swap two numbers in one line, and here we show two methods.

a　+= b　-= a = b　-　a;　//　method　1
printf("After Swapping : %d\t%d", a, b);
(a ^= b), (b ^= a), (a ^= b);　//　method　2
printf("\nAfter Swapping again : %d\t%d", a, b);
