The document provides class declarations for three classes: Time with integer data members secs, mins, hours; Date with integer data members month, day, year; and Circle with integer data members xcenter, ycenter and double data member radius. For each class, it includes a default constructor and parameterized constructor prototype, and a member function showData() to display the data members.

1. Write a class declaration section for each of the following specifications. Include a prototype for
a constructor and a member function named showData() that can be used to display data member
values.
a. A class named Time that has integer data members named secs, mins, and hours
b. A class named Date that has integer data members named month, day, and year
c. A class named Circle that has integer data members named xcenter and ycenter and a double-
precision data member named radius
Solution
a. A class named Time that has integer data members named secs, mins, and hours
class Time{
private:
int secs, mins, hours;
public:
Time(); //default constructor
Time( data_type variable name){ } //parameterised constructor
void showData(){
//print values of secs, mins and hours
}Â Â Â Â };
b. A class named Date that has integer data members named month, day, and year
class Date{

2. private:
int month, day, year;
public:
Date(); //default constructor
Date( data_type variable name){ } //parameterised constructor
void showData(){
//print values of month, day, and year
}Â Â Â Â };
c. A class named Circle that has integer data members named xcenter and ycenter and a double-
precision data member named radius
class Circle{
private:
int xcenter , ycenter;
double radius;
public:
Circle(); //default constructor
Circle( data_type variable name){ } //parameterised constructor
void showData(){
//print values of xcenter ,ycenter and radius
}Â Â Â Â };
