C :

main()  
{ int a,b,c,*p1,*p2,*p3,t;  
scanf("%d%d%d",&a,&b,&c);  
p1=&a;p2=&b;p3=&c;  
if(*p1>*p2)   
{t=p1;p1=p2;p2=t;}  
if(*p1>*p3)  
{t=p1;p1=p3;p3=t;}  
if(*p2>*p3)   
{t=p2;p2=p3;p3=t;}  
printf("%d %d %d ",*p1,*p2,*p3);  
}

C++ :

#include<iostream>
using namespace std;
int main()
{
	int a,M[3],b;
	for(int i=0;i<3;i++){
		cin>>a;M[i]=a;
	}
		for(int j=0;j<2;j++){
 			for(int c=0;c<2-j;c++){
				if(M[c]>M[c+1]){
					b=M[c];
					M[c]=M[c+1];
					M[c+1]=b;
				}
			}
		} 
		for(int i=0;i<3;i++){
			cout<<M[i]<<' ';
		}    
}

Java :

import java.util.Scanner;

public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner input = new Scanner(System.in);
		
		int[] a = new int[3];
		int temp;
		for(int i = 0; i < 3; i ++){
			a[i] = input.nextInt();
		}
		for(int i = 0; i < 2; i ++){
			for(int j = 0; j < 2-i; j ++){
				if(a[j] > a[j+1]){
					temp = a[j];
					a[j] = a[j+1];
					a[j+1] = temp;
					
				}
			}
		}
		for(int i = 0; i < 3; i ++){
			System.out.print(a[i] + " ");
		}
		input.close();
	}
	
	

}

Python :

a = map(lambda x:int(x), raw_input().split())
a.sort()
j = ''
for x in a:

    j+=str(x )+ ' '

print j
