Answer to Question #197947 in C++ for mohib

Question

Create a class called Time that has separate int member data for hours, minutes,

and seconds. One constructor should initialize this data to 0 (default constructor),

and another should initialize it to fixed values (overloaded constructor). Another

member function should display it, in hh:mm:ss (hours: minutes: seconds) format.

Also write the destructor of this class. Write the program that creates three

objects (t1, t2 and t3) of the class to display the time. Initialize t1 using default

constructor, t2 with overloaded constructor and t3 with the values of t2

Answer 1

#include <iostream>

class Time {
public:
    Time()
        : hours_(0)
        , minutes_(0)
        , seconds_(0)
    {}
    
    Time(int hours, int minutes, int seconds)
        : hours_(hours)
        , minutes_(minutes)
        , seconds_(seconds)
    {}

    Time(const Time& time)
        : hours_(time.hours_)
        , minutes_(time.minutes_)
        , seconds_(time.seconds_)
    {}

    ~Time() {
        // default destructor
    }

    void Display() const {
        std::cout << (hours_ <= 9 ? "0" : "") << hours_ << ":";
        std::cout << (minutes_ <= 9 ? "0" : "") << minutes_ << ":";
        std::cout << (seconds_ <= 9 ? "0" : "") << seconds_;
    }

private:
    int hours_;
    int minutes_;
    int seconds_;
};

int main() {
    Time t1, t2(1, 10, 20), t3(t2);
    std::cout << "t1: ";
    t1.Display();
    std::cout << "\nt2: ";
    t2.Display();
    std::cout << "\nt3: ";
    t3.Display();
    return 0;
