Modify the code from last week's Gradebook assignment with Arrays and Functions, to include a two$-$dimensional array for $3$ students and $5$ test scores per student.

Adjust the logic to drop the high score and the low score and average the remaining three scores for each student. The grade is based on the average of the $3$ middle scores.

All data is read in from the keyboard.

Two global constants may be utilized: one for number of students and one for number of tests.

Display in a table format the student's name, $5$ test scores, average, and grade. Include a header in the table to label each column respectively.

Use iomanip and setw$()$ to format the output.

Main should consist of variable declarations and function calls. This means the for loops to process the arrays resides in the functions, not in main.

Here is my initial code, having issues trying to implement the bool validation.
