Hello, I have a bug in my code, and when I run it should ask the user to enter the month and then the year and then print out the calendar for the chosen month and year. My problem with my code is that when I run it and I enter the month, it doesn't ask me for the year and it prints all the years of the month I chose. Please help!

Code:

#include "calendarType.h"
#include <iostream>

using namespace std;

int main()
{
   int month;
   int year;
   int SENTINEL = -9999;
   int userSent = 0;

   while (userSent != SENTINEL)
   {

       cout << "Please enter a month: ";
       cin >> month;
       cout << "\n";

       cout << "Please enter a year: ";
       cin >> year;
       cout << "\n";

       calendarType cal(month, year); //for 2014, first day for each month,
       //6 is sunday
       //9 is monday
       //4 tuesday
       //10 wednesday
       //5 is thursday
       //8 is friday
       //11 is saturday

       cal.printCalendar();

       cout << "If you would like to continue, type 0 and hit enter. " << "\n" << "If you would like to quit, type -9999 and hit enter. ";
       cin >> userSent;
       cout << "\n";

   }

   system("pause");

   return 0;
}

Answer #1

Your code is working fine. Maybe you are compiling it wrong. I ran the compiling command - g++ -o main main.cpp calendarTypeImp.cpp dateTypeImp.cpp extDateTypeImp.cpp dayTypeImp.cpp. Then I ran the programme using - ./main. The attached image shows the input and output of the programme.
