C :

#include<stdio.h>   

int main(){ 
	int a,b,c;
	scanf("%d %d %d",&a,&b,&c);
	
	if(a < b){
		int t = a;
		a = b;
		b = t;
	}
	
	if(b < c){
		int t = b;
		b = c;
		c = t;
	}
	
	if(a < b){
		int t = a;
		a = b;
		b = t;
	}
	
	printf("%d %d %d",a,b,c);

	return 0;
} 

C++ :

#include<iostream>
using namespace std;
int main(){
	int a,b,c,t;
	cin>>a>>b>>c;
	if(a>b){
		t=a;
		a=b;
		b=t;
	}
	if(b>c){
		t=b;
		b=c;
		c=t;
	}
	if(a>b){
		t=a;
		a=b;
		b=t;
	}
	cout<<c<<" "<<b<<" "<<a<<endl;
}

Pascal :

var a,b,c,t:longint;
begin
  read(a,b,c);
  if a<b then begin t:=a;a:=b;b:=t; end;
  if b<c then begin t:=b;b:=c;c:=t; end;
  if a<b then begin t:=a;a:=b;b:=t; end;
  writeln(a,' ',b,' ',c);
end.

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		@SuppressWarnings("resource")
		Scanner scanner=new Scanner(System.in);
		int x=scanner.nextInt();
		int y=scanner.nextInt();
		int z=scanner.nextInt();
		int max=0;
		if (x>y) { 
		max=x;
		x=y;
		y=max;}
		
		if (x>z) {
			max=z;
		   z=x;
		   x=max;
		   }
		if (y>z) {
			max=y;
			y=z;
			z=max;}
		
		System.out.print(z+" "+y+" "+x);	
		}
}

Python :

a,b,c = map(int,input().split());
# a>b>c
if a < b:
    t=a
    a=b
    b=t 
if a < c:
    t=a
    a=c
    c=t 
if b < c:
    t=b
    b=c
    c=t
print(a,b,c)
