C++ :

#include<bits/stdc++.h>
using namespace std;
int a,b,t;
int main()
{
    cin>>a>>b;
    for(int i=a;i<=b;i++)
    {
    	if(i%5==0&&i%6==0)
    	{
    		t++;
    		cout<<i<<" ";
    		if(t==10)cout<<"\n",t=0;
		}
	}
    return 0;
}

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO 自动生成的方法存根
		Scanner input=new Scanner(System.in);
		int a=input.nextInt();
		int b=input.nextInt();
		int i=1;
		while(a<b){
			if(a%5==0 && a%6==0){
				if(i<10){
					System.out.print(a+" ");
					i=i+1;
				}
				else{
					System.out.print(a+"\n");
					i=1;
				}
			}
			a=a+1;
		}
	}
