please write code in $($c$++)$Develop a function to gather $8$ letter grades and store them in an array of characters.

Create a function that accepts a letter grade $($of type character$)$ as its parameter and return an

integer value corresponding to each grade. This function should return zero if an invalid character

is provided.

Establish a function that generates an array of scores $($of type integer$)$ based on the array of letter

grades created in step $1.$ This module will utilize the function crafted in step $2$ to convert each

letter grade into a score.

Design a function to accept an array of integers of size $8$ and return a boolean value indicating if

no grade is below $65.$

Develop functions for all other primary tasks, including computing all averages, determining the

average score of upper$-$level courses, counting the number of courses above $85,$ displaying output,

etc.

Now, utilize the created functions to carry out all the tasks accomplished for the midterm exam.

Construct a loop to prompt the user for the number of applicants before gathering the information

for each applicant and computing their scores.

Don't forget to develop functions for all significant tasks. Additionally, employ the formatting and

styles for your code that you've learned throughout the semester, and be sure to incorporate

comments to clarify your code.
