Classes & Objects

Create a class named Student that has three private member: string firstName string lastName int studentID

Write the required mutator and accessor methods/functions (get/set methods) to display or modify the objects.

In the 'main' function do the following (1) Create a student object "student1".

(2) Use set methods to assign

• StudentID: 6337130
• firstName: Sandy
• lastName: Santos

(3) Display the students detail using get functions in standard output using cout:

Sandy Santos 6337130

#include<iostream>

using namespace std;

class Student{

    private:
        string firstName;
        string lastName;
        int studentID;
    
    public:
    
        // Getter functions.
        string getFirstName(){
            return firstName;
        }
        string getLastName(){
            return lastName;
        }
        int getStudentID(){
            return studentID;
        }
        
        // Setter functions.
        void setFirstName(string FirstName){
            firstName = FirstName;
        }
        void setLastName(string LastName){
            lastName = LastName;
        }
        void setStudentID(int StudentID){
            studentID = StudentID;
        }

};

int main(){
    // Create Student object
    Student student1;

    // Use set functions to set fields.
    student1.setFirstName("Sandy");
    student1.setLastName("Santos");
    student1.setStudentID(6337130);

    // Using get methods to print.
    cout<<student1.getFirstName()<<" "<<student1.getLastName()<<" "<<student1.getStudentID()<<endl;

    return 0;
}
