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.

Fix and modify the code
- 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 last_name = ""; // Last name
string first_name = ""; // First 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.
