#include <iostream>
#include <fstream>
using namespace std;
int main()
{
try{
    int a,b,c;
    cout << "enter the integers" << endl;
    cin>>a>>b;
    cout<<a/b;
    if(b==0){
        cout<<"Not infinite";
    }
        else {
                throw 505;
        }
    }
    catch(int b){
    cout<<" Number greater than zero\n";
    }

    }
    else {
        cout<<"File created successfully!";
