C :

#include<stdio.h>
int main(){
  int n;
  scanf("%d",&n);
  if(n%3==0 && n%5==0)
    printf("can\n");
  else 
    printf("cannot\n");
  return 0;}

C++ :

#include <stdio.h>
int main() {
	int n;
	scanf("%d", &n);
	if (n % 3 == 0 && n % 5 == 0)
		printf("can\n");
	else
		printf("cannot\n");
	return 0;
}

Pascal :

var n:longint;
begin
  readln(n);
  if (n mod 3=0)and(n mod 5=0) then writeln('can') else writeln('cannot');   
end.  

Java :

import java.util.Scanner;
public class Main {
 public static void main(String[] args) {
		Scanner s=new Scanner(System.in);
		int a=s.nextInt();
		if(a%3==0&&a%5==0){
			System.out.println("can");
		}else 	System.out.println("cannot");

	}

}

Python :

n = input()
if n%3==0 and n%5==0:
  print "can"
else:
  print "cannot"

C# :

using System;
namespace C语言
{
    class _2_9
    {
        private static void Main()
        {
            int n=int.Parse(Console.ReadLine());
            if(n%3==0&&n%5==0)
                Console.WriteLine("can");
            else Console.WriteLine("cannot");
  
            Console.ReadLine();        
        }
    }
}
