Please help me with this.

Write a program that will solve the following:

A teacher has five students who have taken four Exams. The teacher uses the following grading scale to assign a letter grade to each student, based on the average of the four exams:

$90-100,$ A

$80-89,$ B

$70-79,$ C

$60-69,$ D

$0-59,$ F

This program uses several parallel arrays. There is an array of strings to hold the $5$ student names and $4$ arrays of $5$ elements each $($doubles$),$ one entry per student in each array at the common index $($review the material in the Powerpoint for the class for ch$.7,$ section $7\mathrm{.}7,$ slides $49-54),$ to hold the exam scores for each student. The student names and exam scores will be read from a file called Grading.txt$.$ You will incorporate the code for doing this into its own function called GetData$(),$ with appropriate parameters that will be called from main$()$ once for each of the $5$ students for which name and exam data are needed.

The format of the Grading.txt file will be as follows:

firstName lastName

examValue$1$

examValue$2$

examValue$3$

examValue$4$

and there will be a block of $5$ lines of data like this for each of the $5$ students.

Other arrays you will need include an array of characters to hold the $5$ students letter grades and an array of $5$ doubles to hold the $5$ student averages $($round up if $\mathrm{.}5$ or above, down if $\mathrm{.}49$ or less$).$

One all the entries have been made from the input file Grading.txt using the newly created function GetData$(),$ you will need a function called CalcAvg$(),$ with appropriate parameters based on each students set of exam grades in that array. You should also determine the letter grade in this function.

Finally, you will need a function to display the name of each student, along with their average and letter grade to the screen, DisplayData$(),$ with appropriate parameters.

Structure of program:

$1)$ your main$()$ should just essentially initialize variables as needed and call other functions

$2)$ the input of data from the text file into the arrays should be handled in one function, GetData$(),$ with appropriate parameters

$3)$ the calculation of the average for each student and their assignment of letter grade should be handled in one function, CalcAvg$(),$ with appropriate parameters

$4)$ the display of the output should be done in another function, DisplayData$(),$ with appropriate parameters
