Question

This challenge is designed to reinforce the skills you leamed about classes and objects. In this challenge, you're going to create a movie class. The movie class will ask the user for the name of their top three favorite movies, what year the movie was released, and what was the rating, whether it was G for General Audience, PG for Parental Guidance, R for Restricted, or M for Mature. I want you to also add logic to make sure it's a valid year. Add the logic into the movie class, not in the main program. Then, write a main program that will ask the user for there three favorite movies and then print out a list when you're done.
C++ language

Answer 1

Here is the program in C++. A point to note here is that, I've added some default behaviour in case when year is not valid. It will automatically set the releaseYear to 2000 (apart from printing an error on the screen).

Code:

#include <iostream>
#include <string>

using namespace std;

// Movie class
class Movie
{
// private variables to hold movie related info.
private:
string name;
string rating;
int releaseYear;

// public methods to set or get movie info.
public:

void setName(string movieName)
{
name = movieName;
}
  
string getName()
{
return name;
}
  
void setRating(string movieRating)
{
rating = movieRating;
}
  
string getRating()
{
return rating;
}
  
void setReleaseYear(int year)
{
// apparently, first movie was released in the year 1906.
if(year > 1906 && year < 2018)
{
releaseYear = year;
}
  
// if the release year is not valid, we'll print an error and set it to 2000 by default.
else
{
cout<<"Year "<<year<<" is invalid. A default year 2000 is being set instead.";
releaseYear = 2000;
}
}
  
int getReleaseYear()
{
return releaseYear;
}
  
};

int main()
{
// create 3 movie objects.
Movie m1, m2, m3;

// temporary variables to hold data read from input.
string movieName, rating;
int releaseYear;

// take 1st movie date and assign to m1.
cout<<"Enter 3 of your favorite movies:"<<endl;
cout<<"Name of the 1st movie: ";
cin>>movieName;
cout<<"What type of rating it has? (G, PG, R or M): ";
cin>>rating;
cout<<"When (which year) was it released? ";
cin>>releaseYear;

m1.setName(movieName);
m1.setRating(rating);
m1.setReleaseYear(releaseYear);


// take 2nd movie date and assign to m2.
cout<<"Name of the 2nd movie: ";
cin>>movieName;
cout<<"What type of rating it has? (G, PG, R or M): ";
cin>>rating;
cout<<"When (which year) was it released? ";
cin>>releaseYear;

m2.setName(movieName);
m2.setRating(rating);
m2.setReleaseYear(releaseYear);


// take 3rd movie date and assign to m3.
cout<<"Name of the 3rd movie: ";
cin>>movieName;
cout<<"What type of rating it has? (G, PG, R or M): ";
cin>>rating;
cout<<"When (which year) was it released? ";
cin>>releaseYear;

m3.setName(movieName);
m3.setRating(rating);
m3.setReleaseYear(releaseYear);


// display the same information.
cout<<endl<<"Your favorite movies are:"<<endl;

cout<<"Movie: "<<m1.getName()<<endl;
cout<<"Rating: "<<m1.getRating()<<endl;
cout<<"Release Year: "<<m1.getReleaseYear()<<endl;

cout<<"Movie: "<<m2.getName()<<endl;
cout<<"Rating: "<<m2.getRating()<<endl;
cout<<"Release Year: "<<m2.getReleaseYear()<<endl;

cout<<"Movie: "<<m3.getName()<<endl;
cout<<"Rating: "<<m3.getRating()<<endl;
cout<<"Release Year: "<<m3.getReleaseYear()<<endl;

return 0;

}
