  • Using the attached code as a "model", write a program where each student record is constructed using the class StudentRec.
    • The variables in this case are "private" and the functions are "public."
    • Note: only the first_name and last_name variables will require "getter" functions that return the name in all caps:

get_first_name_upper() and get_last_name_upper() functions.

  • Your class declaration section should look something like this:

class StudentRec

{

private

string first_name = ""; // First name

string middle_name = ""; // Middle name

string last_name = ""; // Last name

int year_grad = 0; // Year expected to graduate

float gpa = 0.0; // Current gpa

public:

void set_last_name(string last_name_param);

string get_last_name() const;

string get_last_name_upper() const;

// the rest of the "setter" and "getter" functions for each variable above go here

}; // NOTE: a class declaration ends with a semicolon

  • The program should ask for the data to fill a studentRec of structure StudentRec and then ask y/n if they want to add another studentRec.
    • Each studentRec will go into the vector of type StudentRec called student_list.
  • After the student records have been entered into the vector student_list, find the average gpa of all the students in the vector.
  • Output all the student records and give the average gpa for the students. Use the iomanip tools to make the data look as nice a possible.
  • Write excellent comments:
    • At the top to show your name, the class, and what the program does.
    • For each function.
    • Critical or tricky parts that might be difficult to understand without a comment.
