DO IT IN C++

### Programming Exercise: Class Definitions and Main Function #### Task Overview: Create two classes and a main function, and save the file as `<lastname>+PR1.cpp` using the following instructions for class definitions and main functionality. #### Class Definitions: **Course** - **Attributes:** - `+number` (string) - `+credits` (int; must be a value greater than 0) - **Constructors and Methods:** - Accessors, mutators, default constructor - Default constructor initializes `number` to "CSC101" and `credits` to 3 - Overloaded constructor accepts two parameters for `number` and `credits` **Student** - **Attributes:** - `+name` (string) - `+enroll` (Course) - **Constructors and Methods:** - Accessors, mutators, default constructor - Default constructor initializes `name` to an empty string #### Main Function Instructions: 1. Declare a `string` variable named `cnumber`. 2. Declare an `int` variable named `ccredits`. 3. Declare a `string` variable named `sname`. 4. Instantiate a `Course` object called `c1` using its default constructor. 5. Input a `string` from the keyboard and store it in `cnumber`. 6. Set `c1` object's `number` attribute to `cnumber`. 7. Input an `int` from the keyboard and store it in `ccredits`. 8. Set `c1` object's `credits` attribute to `ccredits`. 9. Create a `Course` object called `c2` using its overloaded constructor with `number` set to "CSC350" and `credits` set to 4. 10. Create another `Course` called `c3` using its default constructor. 11. Set `c3` object's `number` attribute to "ELECTIVE". 12. Set `c3` object's `credits` to the sum of `c1` and `c2` objects' `credits`. 13. Declare a `Student` object called `s1` using the default constructor. 14. Input a `string` from the keyboard and store it in `sname`. 15. Set `s1` object's `name` attribute to `sname`. 16. Set `s1` object's `enroll`
