Question

C++. I need to alter this code below to the current specifications.

Console

Progressing Complete!!!

Specifications

• Included is an input file.
• Included is a function to aide, if needed
• Use the functions, enum, and namespace defined in Assignment 6.
• You will need to use a loop to read each student’s data
• You will need to load every homework grade into an array
• Calculate the homework average
• The homework average can be calculated while the array is loaded
• Move the printing of the report card into a function and pass the variables read.
• This includes passing an array of the homework grades
• Fields will include: output file, first name, last name, grade level, homework array, homework average, midterm exam, final exam, present and absence.
• This print function should call the other functions from Assignment 6.
• Assume the data in the input files is valid data.

According to the given specifications,the changes made are:

A homework array of size 10 is initialized and loaded through a for loop from input file.Also, sum of each homework marks are simultaneously by adding each element of array to homeworksum variable.

A new function for printing report is created and necessary variables are passed including the homework array.
