C :

#include<stdlib.h>
int compara(int *pa,int *pb,int *pc)
{
	int temp1,temp2,temp3;

}
int main()
{
	int a,b,c;
	scanf("%d%d%d",&a,&b,&c);

}

C++ :

#include <stdio.h>
int main() {
	void swap(int * pt1, int * pt2);
	int *p1, *p2, *p3, a, b, c;
	scanf("%d %d %d", &a, &b, &c);

	printf("%d %d %d\n", *p1, *p2, *p3);
	return 0;
}
void swap(int * pt1, int * pt2) {
	int temp;
	temp = *pt1;
	*pt1 = *pt2;
	*pt2 = temp;
}

Pascal :

var
  a:array[1..3] of longint;
  i,j,t:longint;
begin
  for i:=1 to 3 do read(a[i]);
  for i:=1 to 2 do
    for j:=i+1 to 3 do
      if (a[i]<a[j]) then
        begin t:=a[i]; a[i]:=a[j]; a[j]:=t; end;
  for i:=1 to 2 do write(a[i],' ');
   writeln(a[3]);
end.

Java :

import java.util.*;

public class Main{
	public static void main (String[] args) {
		Scanner in=new Scanner(System.in);
		int []a=new int [3];
		for(int i=0;i<3;i++){

		java.util.Arrays.sort(a);
		System.out.print (a[2]+" ");
		System.out.print (a[1]+" ");
