Question

C++ program homework question 1

1. Create and implement a class called clockType with the following data and methods (60 Points.):

• Data:
  • Hours, minutes, seconds
• Methods:
  • Set and get hours
  • Set and get minutes
  • Set and get seconds
  • printTime(…) to display time in the form of hh:mm:ss
  • default and overloading constructor

2. Overloading Operators:
   • << (extraction) operator to display time in the form of hh:mm:ss
   • >> (insertion) operator to get input for hours, minutes, and seconds
   • operator+=(int x) (increment operator) to increment by x seconds
   • operator<=(…) which returns true if time of the clock is less than or equal to another clock
   • operator>=(…) which returns true if time of the clock is greater than or equal to another clock

Derive a new class called extClockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors and implement them

Answer 1

Please find the code , output below.

#include <iostream>
#include <bits/stdc++.h>
using namespace std;
// Class declaration
class clockType {
  
public:
int hours, minutes, seconds;
clockType (int hours1, int minutes1, int seconds1){
hours=hours1;
minutes=minutes1;
seconds=seconds1;
}
void sethours(int hours1){
hours=hours1;
}
void setminutes(int minutes1){
minutes=minutes1;
}
void setseconds(int seconds1){
seconds=seconds1;
}
int gethouors(){
return hours;
}
int getminutes(){
return minutes;
}
int getseconds(){
return seconds;
}
// Printing the output
void printTime(){
if(hours<10 && minutes>=10 && seconds >=10){
cout<<"The time is 0"<<hours<<" : "<< minutes<< " : "<<seconds<<endl;
}
else if (hours>=10 && minutes < 10 && seconds>=10){
cout<<"The time is "<<hours<<" : 0"<< minutes<< " : "<<seconds<<endl;
}
else if (hours>=10 && minutes >= 10 && seconds <10){
cout<<"The time is "<<hours<<" : "<< minutes<< " : 0"<<seconds<<endl;
}
else if (hours>=10 && minutes < 10 && seconds <10){
cout<<"The time is "<<hours<<" : 0"<< minutes<< " : 0"<<seconds<<endl;
}
else if (hours <10 && minutes >= 10 && seconds <10){
cout<<"The time is 0"<<hours<<" : "<< minutes<< " : 0"<<seconds<<endl;
}
else if (hours <10 && minutes < 10 && seconds >=10){
cout<<"The time is 0"<<hours<<" : 0"<< minutes<< " : "<<seconds<<endl;
}
else if (hours<10 && minutes < 10 && seconds <10){
cout<<"The time is 0"<<hours<<" : 0"<< minutes<< " : 0"<<seconds<<endl;
}
else{
cout<<"The time is "<<hours<<" : "<< minutes<< " : "<<seconds<<endl;
}
}
};
// Child class
class extClockType : public clockType {
public:
vector<string> time_zone;
extClockType(int hours1, int minutes1, int seconds1,string timezone): clockType(hours1,minutes1,seconds1){
time_zone.push_back(timezone);
}
void printTimezone(){
cout<<"\nThe timezone is "<<time_zone[0];
}
};

int main()
{   
// Getting input from user
int hours, minutes, seconds;
cout<<"Enter the hours : ";
cin>>hours;
if(hours<0 || hours>24){
cout<< "Invalid hours !!!";
exit(0);
}
cout<<"Enter the minutes : ";
cin>>minutes;
if(minutes<0 || minutes>60){
cout<< "Invalid minutes !!!";
exit(0);
}
cout<<"Enter the seconds : ";
cin>>seconds;
if(seconds<0 || seconds>60){
cout<< "Invalid seconds !!!";
exit(0);
}
// Creating object of clockType class
clockType ct(hours,minutes,seconds);
  
//ct.printTime();
extClockType ect(hours,minutes,seconds,"Pacific");
// Calling the function
ect.printTime();
ect.printTimezone();
return 0;
}
