Question

Create a structure course with some attributes i.e course_ID, course_title, credit_hrs etc.. Then Implement following 5 functions (Known as CRUDS operations which means CREATE, READ, UPDATE, DELETE, SEARCH operations):

1. addAStudent

2. updateAStudent

3. deleteAStudent

4. searchAndDisplayAStudent

5. displayAllstudents

After that, create an array of 5 courses in main function. Create a menu in main function to enable user to select and perform the operations we created above. Program must not exit until and unless user wants to do so.

Answer 1

struct Course
{
public:
	void addAStudent(string sname)
	{
		students.push_back(sname);
	}
	void updateAStudent(int sID,string sname)
	{
		students[sID] = sname;
	}
	void deleteAStudent(int sID)
	{
		students.erase(students.begin() + sID);
	}
	void searchAndDisplayAStudent(int sID)
	{
		cin >> sID;
		cout << students[sID] << endl;
	}
	void displayAllstudents()
	{
		for (int i = 0; i < students.size(); i++)
		{
			cout << students[i] << endl;
		}
	}
private:
	int course_ID;
	string cousre_title;
	int credit_hrs;
	vector<string> students;
};
