C :

#include<stdio.h>
void a_b(int *p,int *q)
{
	if(*p<*q)
		printf("%d %d\n",*q,*p);
	if(*p>=*q)
		printf("%d %d\n",*p,*q);
}
int main()
{
	int a,b;
	scanf("%d%d",&a,&b);
	a_b(&a,&b);
	return 0;
}

C++ :

#include <stdio.h>
int main() {
	int *p1, *p2, *p, a, b;
	scanf("%d %d", &a, &b);
	p1 = &a; p2 = &b;
	if (a < b) {
		p = p1; p1 = p2; p2 = p;
	}
	printf("%d %d\n", *p1, *p2);
	return 0;
}

Pascal :

uses math;
var 
  a,b:longint;
begin
  readln(a,b);
  writeln(max(a,b),' ',min(a,b));
end.

Java :

import java.util.*;

public class Main{
	public static void main (String[] args) {
		Scanner in=new Scanner(System.in);
		int a=in.nextInt();
		int b=in.nextInt();
		if(a>b)
			System.out.println (a+" "+b);
		else
			System.out.println (b+" "+a);
	}
}
