C :

#include<string.h>
#include<stdio.h>
int main()
{
    int m;
    char a[100];
    scanf("%s",a);
    m=strlen(a);
   if(m==10)
       printf("shi yi");
    if(m==9)
        printf("yi");
    if(m==8)
        printf("qian wan");
    if(m==7)
        printf("bai wan");
    if(m==6)
        printf("shi wan");
    if(m==5)
        printf("wan");
    return 0;
}

C++ :

#include <iostream>
using namespace std;
int main()
{
	long int n;
	cin>>n;
	if(n >= 10000 && n <= 9999999999)
	{
		if(n >= 10000 && n < 100000)
			cout<<"wan";
		else if(n >= 100000 && n < 1000000)
			cout<<"shi wan";
		else if(n >= 1000000 && n < 10000000)
			cout<<"bai wan";
		else if(n >= 10000000 && n < 100000000)
			cout<<"qian wan";
		else if(n >= 100000000 && n < 1000000000)
			cout<<"yi";
		else
			cout<<"shi yi";
	}
	
	return 0;
} 

Pascal :

var a:string;
b:longint;
begin
read(a);
b:=length(a);
if b=5 then write('wan')
else if b=6 then write('shi wan')
else if b=7 then write('bai wan')
else if b=8 then write('qian wan')
else if b=9 then write('yi')
else write('shi yi');
end.

Java :

import java.util.*;
public class Main {
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		long n = sc.nextInt();
		int count = 0;
		while(n > 0){
			n = n / 10;
			count++;
			}
			if(count == 10){
				System.out.println("shi yi");
			}
			if(count == 9){
				System.out.println("yi");
			}
			if(count == 8){
				System.out.println("qian wan");
			}
			if(count == 7){
				System.out.println("bai wan");
			}
			if(count == 6){
				System.out.println("shi wan");
			}
			if(count == 5){
				System.out.println("wan");
			}
		
	}
}	

Python :

n = int(input())
if 10000 <= n < 100000:
    print('wan')
elif 100000 <= n < 1000000:
    print('shi wan')
elif 1000000 <= n < 10000000:
    print('bai wan')
elif 10000000 <= n < 100000000:
    print('qian wan')
elif 100000000 <= n < 1000000000:
    print('yi')
elif 1000000000 <= n < 10000000000:
    print('shi yi')
