after the second output statement, the program doesn't take the second set of inputs. Any idea what I could even do to fix this? Is this just a quirk of C ? Any help at all is much appreciated. :)

#include <iostream>
using namespace std;

int main()
{
    int startHours, startMinutes;
    int endHours, endMinutes;
    bool startIsAM, endIsAM;
    char amPmChar, extra;

    
    
    int computeDifference(int startH, int startM, bool startTime, int endH, int endM, bool endTime);

    int diff, hours, minutes;

    //----------------------------------------------------------------------//

    cout << "Enter start time, in the format 'HH:MM xm', where 'xm' is\n either 'am' or 'pm' for AM or PM: ";
    cin >> startHours;
    cin >> extra;
    cin >> startMinutes;
    cin >> amPmChar;

    startIsAM = (amPmChar == 'A') || (amPmChar == 'a');

    cout << "Enter future time in the format 'HH:MM xm' where 'xm' is\n either 'am' or 'pm': ";
    cin >> endHours;
    cin >> extra;
    cin >> endMinutes;
    cin >> amPmChar;
}

CodePudding user response：

You have to read one more char, because when you read amPmChar from the input - m is still in your stream. And after that - there is an endline, so your endHours tries to initialize with that value. That's your problem. You may read more about it in this answer, it's about cin validation.
