private:
string m_studentName = " "; // "m_ is" for member variables so any varibale insied
class
// are known to any fucntion that
will be later on defined in class,
// those variable can be used in
any functions inside of class
int m_studentId = 0; // its to avoid confuion
bool m_enrolled = false;
public: // public indicates these variables aare able to be accessed from outside,
//private mean youu could not access those varibales from outside.
// constructors are used to
initialize variables in your objects,
// so it makes sense sense to pass
calues into a construcot wih are then
// used to intialize variables
inside of that consturcots
// should initialize all member
values
//constucotrs
student(); // constructor 1
student(string studentName); // constructor 2
student(string studentName, int studentId); // constructor 3
// function with the same name as the class is the constructor
// setters, modifies values of vaiables, mutator
void setStudentName(string studentName){m_studentName = studentName;} // inline
func where func in defined inside the class not outside}
