[C++] Problema con While

[zergling]

Ciao a tutti,
Sto scrivendo un programma che sia in grado di convertire l'ora in 24h in 12h... Mi sono creato 3 funzioni e tutto fila liscio fino a quando devo eseguire il while loop in main :(
Come faccio ad useguire il while loop che mi consenta di richiamare le mie tre funzioni? E' possibile?
Ciao e grazie :D

#include <iostream>

using namespace std;

void input(int& hour, int& minutes);
char conversion(int& hour, char& day_night);
void output(int hour, int minutes, char day_night, char& answer);

int main()
{
int hour, minutes;
char day_night, answer;

do
{
input(hour, minutes);
conversion(hour, day_night);
output(hour, minutes, day_night, answer);
}while((answer == 'y')||(answer == 'Y'));

return 0;
}
void input(int& hour, int& minutes)
{
bool check = false;
while (((hour >24) || (hour < 0)) || ((minutes < 0)||(minutes > 59)))
{
if (check == true)
{
cout << "\nEnter minutes: ";
cin >> minutes;
if((minutes > 60) || (minutes < 0))
{
cout << "ERROR! Minutes can not be " << minutes << endl;
continue;
}
}

else
{
cout << "Enter hour in 24h notation: ";
cin >> hour;

if((hour >24) || (hour < 0))
{
cout << "ERROR! Hour can not be " << hour << endl;
continue;
}
else
{
check = true;
cout << "\nEnter minutes: ";
cin >> minutes;
}

if((minutes > 60) || (minutes < 0))
{
cout << "ERROR! Minutes can not be " << minutes << endl;
continue;

}
}
}
}

char conversion(int& hour, char& day_night)
{
if((hour >=13) && (hour <=23))
day_night = 'p';

else if (hour == 24)
day_night = 'a';

else
day_night = 'a';

if(hour > 12)
hour = hour -12;

return hour;
}

void output(int hour, int minutes, char day_night, char& answer)
{
cout << "\nThe time in 12H notation is: ";

if (day_night == 'p')
cout << hour << ":" << minutes << " " << "P.M" << endl;
else
cout << hour << ":" << minutes << " " << "A.M" << endl;

cout << "\nWould you like to run the program again? (y/n)";
cin >> answer;
}

Qualcuno e' in grado di aiutarmi per piacere?

Qualcuno e' in grado di aiutarmi per piacere?

metti il codice nel tag CODE, così si capisce poco.

Cool Non conoscevo la funzione TAG
GRAZIE per avermi risposto :D

Hmmm che faccio ci rinuncio oppure qualcuno sa come aiutarmi?
