Question
Modify project #4 by using modular programming principle: Divide the main function written for the project #4 into nine functions which are explained below. The number of students (n) will be declared global. Also, use global constants for the size of arrays. The numeric arrays and non-numeric array must be passed through parameters/arguments. Note that arrays are passed by reference only. The main function will be placed first. Therefore, you will need to declare prototypes of functions. Use your own student’s data and names of arrays. The description of functions is given below:
Function main: It will include proper declarations. It will read the value of n (the number of students) from the key board and validate using a while loop (The value of n must be at least 3). It will call other functions as needed.
Function inputData: This function will read the data from the input file into proper arrays and then call ValidateData to validate.
Functions validateData: These will be two overloaded functions with same name. One function will validate non-numeric data and the other will validate numeric data.
Function NumGrade: This function will compute and store into proper array elements the numerical grades.
Function LetGrade: This function will compute and store into proper array elements the letter grades.
Function Comments: This function will determine and write commend/warning comments. Function Report: After all computations are completed. Arrays will contain all the information. Pass these arrays to this function which will write to the output file the reports of all students.
