ok guys, i need some help really bad. i have a strange problem w/ my
prog.

//heres the warnings on compliing
D:\PROGS\cppic>gxx -Wall -c ampm_air.cpp
ampm_air.cpp: In method `void airtime::set()':

//here's the prog
// arrayair.cpp
// create an array of airtime objects

#include <iostream.h>
#include <iomanip.h>

enum Day { am, pm };

class airtime
	{
	private:  
		int minutes, hours;
		Day half;
	public:
		void set()
			{
			char dummy;

			cout << "Enter time (ie. 4:45am): ";
			cin >> hours >> dummy >> minutes >> half; 
// i think the previous line is the trouble maker
			hours += minutes / 60;
			minutes %= 60;
			hours %= 12;
			}
		void display()
			{
			cout << hours << ':' << setfill('O') << setw(2) << minutes << half;
			}
	};

void main()
	{
	airtime at[20];
	int n=0;
	char choice;

	do
		{
		cout << "Airtime " << n << ". ";
		at[n++].set();
		cout << "Do another(Y/N) ";
		cin >> choice;
		} while(choice != 'n');

	for(int j=0; j<n; ++j)
		{
		cout << "\nAirtime " << j << " = ";
		at[j].display();
		}
	}
// end prog

	it seems like it is working fine but at the input it just
crashes(badly) leaving a huge list of gibberish and this
