Swap two variables in one line in C/C+
Here is an example of swapping in 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
After Swapping : 828 After Swapping again : 288
In the above program, there are two variables a and b and initialized with the values 28 and 8 respectively. There are so many methods to swap two numbers in one line and we displayed two methods here.
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);
