Alright guys, brand new to the forum and I'm currently taking my first c++ course. I am not asking for anyone to do my homework for me, but I have been working on the same assignment for the past three days and have been unable to figure it out. Here is the link for the assignment:

as well as the code I have so far, any help would be appreciated:

/* -------------------------------------------------------

#include <iostream> // to use cin cout
#include <iomanip> //to set precision, etc.
#include <cmath> // to use predefined math functions

using namespace std;

//list function prototypes so main is first

int convertTime24to12(int hour);
void getTime24();
void printTime12(int& minute, char& ch);
int userWantsToContinue();

//main function to repeat input and output of processing function if desired by user
int main() 
    int hour;
    char ch;
    int minute;

        printTime12(minute, ch);


void getTime24()
    int hour, minute;
    char ch;

    cout << "Please enter time in 24-hour format. For example 22:03: " << endl;
    cin >> hour >> ch >> minute;


int convertTime24to12(int hour) 
    char ch;

    if (hour > 12){
        hour -= 12;
        ch == 'p';

        ch == 'a';

    return hour;

void printTime12(int& minute, char& ch) 
    cout << "The time entered in 12-hour format is " << convertTime24to12;

    if (ch == 'a')
        cout << "a.m.";

        cout << "p.m.";

So what's the error you're getting?

First is it is saying hour is being used uninnitialized from line 30, secondly, after user input, it prints a jumbled number for the 12 hour format which is 00F6109B in the console window.
