Comments on Small integer swapping

Parent

Small integer swapping

+1
−4

In this simple challenge, create a short program that takes 2 ints as input, output them, swap their places, then output them again. Those 2 integers can't be the same number. The program with the shortest solution wins! Loopholes are banned in this challenge.

An example C program for the challenge (mostly ungolfed):

#include <stdio.h>

int main() {
	int x, y;
	scanf("%i %i", &x, &y);
	printf("%i %i", x, y);
	int z = x;
	x = y;
	y = z;
	printf("%i %i", x, y);
}

You can make 2 answers in one post: 1 with output swapping, and 1 with variable swapping.
