College Project Creating a class in C++: Help with the constructor and member functio

Hello, thanks for visiting my thread.

The assignment requires that I create a class named Time. It has 3 data members, hour, minute, and second (all are ints). This class should have a constructor with 3 parameters to initialize the 3 data members. There are required bounds for each data member. The hour value should be in the range 0-23, if not set it to 12. The minute value should be in the range 0-59, if not set it to 0. The second value should be in the range 0-59, if not set it to 0. A set and get function is required for each data member. Lastly, a member function named "displayTime" that displays the hour, minute, and second separated by colons. Additionally, if any of the values in hour, minute, and second are between 0-9 then it needs to display as "00", "01", "02", etc.

My current roadblock is that I don't know how to initialize a class with more than one parameter. There isn't an example in the text or online exercises that I can work from. I've tried modifying an example that initializes a single data member, but the compiler doesn't seem to like it.

The second roadblock I foresee is the displyTime member function. I literally have no concept of what this member function is supposed to look like in terms of the syntax.

My work-in-progess code is:

Program code:

Code:

---

#include <iostream>#include <string>
#include "Time.h"


using namespace std;


int main()
{
    Time theTime(5,10,10);
   
    cout << "Current time is: " << theTime.displayTime();


    cout << "\n Please enter the Hour";
    int theHour;
    cin >> theHour;
    theTime.setHour(theHour);
   
    cout << "\n Please enter the Minute";
    int theSecond;
    cin >> theSecond;
    theTime.setSecond(theSecond);
   
    cout << "\n Please enter the Second";
    int theMinute;
    cin >> theMinute;
    theTime.setMinute(theMinute);   
   
    cout << "Current time is: " << theTime.displayTime();


}

---

Header code:

Code:

---

#include <string>

class Time {


public:
    Time () : hour{0} : minute{0}    : second{0} {
    }
   
void setHour (int theHour) {
    if (theHour < 0 or theHour > 23)
    hour = 12;
    else
    hour = theHour;
}


int getHour () {
    return hour;
}


void setMinute (int theMinute) {
    if (theMinute < 0 or theMinute > 59)
    minute = 0;
    else
    minute = theMinute;
}


int getMinute () {
    return minute;
}


void setSecond (int theSecond) {
    if (theSecond < 0 or theSecond > 59)
    second = 0;
    else
    second = theSecond;
}


int getSecond () {
    return second;
}




private:
    int hour;
    int minute;
    int second;
};

About passing parameters to a ctor: Constructor in C++ - Default Constructor - Parameterized Constructor - Overloaded Constructor
Since you call displayTime without parameters and don't check one it should be void displayTime();

PROGRESS HAS BEEN MADE!!!

After several hours, I got the constructor to work. I also have the set and get functions working, along with the bound restrictions.

Now I have to move onto the member function displayTime. I can write something that's functionally similar using getHour, getMinute, and getSecond such as

Code:

---

cout << "Now the time is: " << theTime.getHour();   
cout << ":" << theTime.getMinute();
cout << ":" << theTime.getSecond();

---

I just got to wrap it into a single member function while accounting for the 01, 02, 03 values.

I have the member function displayTime working, but without the requirement that it display each value for hour, minute, and second as 2 digits. ( 1 second should display as 01, 2 should be 02, etc.

It looks like:

Code:

---

void displayTime () {   
    std::cout << "\n\nNow the time is: " << hour;
    std::cout << ":" << minute;
    std::cout << ":" << second;
}

---

If someone can point me in the right direction to code in the 2 digit display requirement I would appreciate it.

Code:

---

// either do it manually
    if (h < 10) cout << '0';
    cout << h << ':';
    if (m < 10) cout << '0';
    cout << m << ':';
    if (s < 10) cout << '0';
    cout << s << '\n';

// or use the iostream formatting facilities
    cout << setfill('0');
    cout << setw(2) << h << ':';
    cout << setw(2) << m << ':';
    cout << setw(2) << s << '\n';

The project is complete. Thank you to OldGuy2 and john.c for helping.
