Question

On Dev C++ Using the header file provided below "myClock.h", implement a C++ program that present the user with the following menu: "Press 1 to read the time." "Press 2 to enter a new time." "Press 3 to exit." -------------------------------------------------------------- Submit both file, myClock.h and your implementation .cpp myClock.h class myClock { public: myClock(); ~myClock(){}; void setTime(int, int, int); // Add the getter function prototype here . private: int hour; int minute; int second; };

Answer 1

#ifndef CCC_TIME_H
#define CCC_TIME_H

// Defines class myClock to store time
class myClock
{
public:
// Prototype of member functions
myClock();
~myClock(){};
void setTime(int, int, int);
void setHour(int);
void setMinute(int);
void setSecond(int);
int getHour();
int getMinute();
int getSecond();

private:
// Data member to store data
int hour; int minute; int second;
};// End of class

#endif

------------------------------------------------------------------------------------------------

#include "MyClock.h"

// Default constructor to assign default value to data member
myClock::myClock()
{
hour = minute = second = 0;
}// End of default constructor

// Function to assign parameter values to data member
void myClock::setTime(int h, int m, int s)
{
hour = h;
minute = m;
second = s;
}// End of function

// Function to set hour
void myClock::setHour(int h)
{

// Function to set minute
void myClock::setMinute(int m)

// Function to return hour

// Function to return minute
int myClock::getMinute()
{
return minute;
}// End of function

// Function to return second
int myClock::getSecond()
{
