PROBLEM and INSTRUCTIONS

In this assignment, you will develop a C$++$ program to create Student object using the data in the attached $$studentInfo$.$txt$$ file. Then put the Student objects in a ClassRoom object, and use ClassRoom object to perform object$-$oriented programming tasks:

Input data file $$studentInfo$.$txt$----1.$ Create a new C$++$ project $$LastName$\_$Lab$8,$ define class Student, class ClassRoom and test program by adding the following files:

$$ Student.h

$$ Student.cpp

$$ ClassRoom.h

$$ ClassRoom.cpp

$$ TestProgram.cpp

$2.$ Declare the following data members and member function prototypes of class Student in Student.h:

$$ Data members

o First name $($string$)$

o Last name $($string$)$

o Student ID $($string$)$

o First Year GPA $($double$)$

o Second Year GPA $($double$)$

$$ Member functions

o Null Constructor $($no parameters$)$

o Constructor with parameters $(5$ parameters, one for each data member$)$

o Getter and setter functions for each non$-$static data member

o Value$-$returning function called calcAvgGpa which calculates and returns the average of $2$ GPAs.

o Void function called displayStudent which displays a student$$s last name, first name, $2$ GPAs and average GPA.

$3.$ Details$/$Define the member functions of class Student in

Student.cpp:

$$ Null Constructor $($no parameters$)$

o Initialize non$-$static data members to default initial value $($First name, Last name, Student ID should have default value of $,$ GPA$1$ and GPA$2$ should have a default value of $0\mathrm{.}0)$

$$ Constructor with parameters

o Initialize non$-$static data members with the parameters.

$$ Getter and Setter functions for each non$-$static data member

$$ Value$-$returning function called calcAvgGpa to calculate and return the average of $2$ GPA.

$$ Void function called displayStudent to display student$$s last name, first name, $2$ GPA scores and average GPA score $($by calling the calcAvgGpa function$).$

$4.$ Declare the following data members and member function prototypes of class ClassRoom in ClassRoom.h:

$$ Data members

o Number of student objects read$/$added in this classroom $($int$)$

o Array of student objects $($make size is $10$ since there are $10$ students in the file$)$

Student StudentArray$[10]$;

$$ Member functions

o Constructor with classroom name for a parameter $($this can be $$CSC$-134).$

o Getter and setter functions for Number of students, and Array of student objects.

o Void function called readAndCreateStudentArray which creates an array of Student objects by reading student data from input data file.

o Void function called displayAllStudents which displays the header information and calls the displayStudent$()$ function from Student class $($for loop$)$

o Value$-$returning function called calcStudentAvg which calculates and returns the average score of all students.

o Value$-$returning function called getNumStudent which returns the number of student objects.

$5.$ Details$/$Define the member functions of class ClassRoom in

ClassRoom.cpp:

$$ Constructor with $1$parameter

o Initialize classroom name with parameter value.

o Initialize number of students as $0.$

$$ Getter and Setter function for each data member $($Classroom name, Number of student objects$).$

$$ Getter and Setter function for Array of student objects:

o The setter function for the Array of students setStudentArray should request an array of Student objects and number of students as parameters:

void ClassRoom::setStudentArray$($Student students$[],$ int $\_$numStudent$)$

o The getter function for the Array of students getStudentArray$()$ should return an array of Student objects, the return type could be a pointer to Student:

Student$*$ ClassRoom::getStudentArray$()$

$$ Void function called readAndCreateStudentArray which performs the following:
