Write a program that uses a struct named Student to store information about a Student. You will be reading from a text input file into an array $($size $20)$ of Student structs. The program will contain the following files:

main.cpp contains the main function for testing the program.

Student.h and Student.cpp represent a classroom student struct, which has three data members:

first name, last name, and GPA.

students, txt $-$ Text file with student information

$(1)$ Build the Student struct with the following specifications in the files $($Student$.h$ and Student.cpp$)$:

char firstName$[101]$

char lastName $[101]$

double gpa;

You may NOT use strings.

$(2)$ Create the following functions $($Student$.h$ and Student.cpp$)$:

void loadValues$($ifstream &inFile, Student studentList$[,$ int &numStudents$)$; $//$ reads from file, populates the array, updates the number of students in the array

void printValues$($Student studentList$],$ int numStudents$)$; $//$ prints the contents of the array

$(3)$ In main $()($main$.$cpp$),$ open the students.txt file and pass to the loadvalues $()$ function to read the student data into the array. Then call the printValues $()$ function to print out the list of students.

$(4)$ Program input and output:

File input, students $.$ txt:

Henry; Nguyen; $3\mathrm{.}5$

Brenda; Stern; $2\mathrm{.}0$

Lynda; Robison; $3\mathrm{.}2$

Sonya;King; $3\mathrm{.}9$

Program output:

$\backslash$table$[[$Henry$,$Nguyen,$3\mathrm{.}5],[$Brenda$,$Stern,$2\mathrm{.}0],[$Lynda$,$Robison,$3\mathrm{.}2]]$

$(5)$ Notes:

Add the struct definition before the function prototypes! Check out Structs and Array Example, Section $14\mathrm{.}4$

Make sure to have #include main$()=0$;
