Programming Example
Define a class named movieMagic with the following description:
Study this program carefully to understand the logic, output, and explanation in a structured way.
Define a class named movieMagic with the following description:
| Data Members | Purpose |
|---|---|
| int year | To store the year of release of a movie |
| String title | To store the title of the movie |
| float rating | To store the popularity rating of the movie (minimum rating=0.0 and maximum rating=5.0) |
| Member Methods | Purpose |
|---|---|
| movieMagic() | Default constructor to initialize numeric data members to 0 and String data member to "". |
| void accept() | To input and store year, title and rating |
| void display() | To display the title of the movie and a message based on the rating as per the table given below |
| Rating | Message to be displayed |
|---|---|
| 0.0 to 2.0 | Flop |
| 2.1 to 3.4 | Semi-Hit |
| 3.5 to 4.4 | Hit |
| 4.5 to 5.0 | Super-Hit |
Write a main method to create an object of the class and call the above member methods.

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
