Question
Rewrite the addStudent function in C++ so that the Course class in the attached file to throw a runtime_error if the number of students exceeds the capacity.
![```cpp
#include <iostream>
#include "Course.h"
using namespace std;
Course::Course(const string& courseName, int capacity)
{
numberOfStudents = 0;
this->courseName = courseName;
this->capacity = capacity;
students = new string[capacity];
}
Course::~Course()
{
delete [] students;
}
string Course::getCourseName() const
{
return courseName;
}
void Course::addStudent(const string& name)
{
students[numberOfStudents] = name;
numberOfStudents++;
}
void Course::dropStudent(const string& name)
{
// Left as an exercise
}
string* Course::getStudents() const
{
return students;
}
int Course::getNumberOfStudents() const
{
return numberOfStudents;
}
```
### Explanation:
This code defines a class `Course` in C++. It includes functionalities for managing a course with students:
- **Constructor** (`Course::Course`): Initializes the course with a name and capacity, setting the initial number of students to zero, and allocating memory for the list of students.
- **Destructor** (`Course::~Course`): Deletes the allocated memory for students when the course object is destroyed.
- **`getCourseName` function**: Returns the name of the course.
- **`addStudent` function**: Adds a student to the course by name. Increments the `numberOfStudents`.
- **`dropStudent` function**: Placeholder function for removing a student from the course, left as an exercise.
- **`getStudents` function**: Returns the list of students in the course.
- **`getNumberOfStudents` function**: Returns the current number of students in the course.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F09af1c01-6e60-4588-9390-2a0cbfc62f20%2F23144126-65e3-4d58-8b3e-d10a91fc3e5b%2F0vak6ms_processed.jpeg&w=3840&q=75)
