Answer using c++ programming language.

Objective:

The purpose of this lab project is to expose you to structures and classes.

Problem Specification:

Using a structure:

You are to write a program that will define a structure consisting of the following data members, fields:

• Name - a string
• Student id number an integer.
• Three test scores positive short integers.
• Average a float
• Grade a character.

Input to the program consists of:

• name
• id number
• three test scores

Requirements:

• Use a function to read the name, id number and three test scores, the function will return a structure.
• A function to find the average, the function is a void function that takes the entire structure as an argument (by reference) and calculates the average.
• A function that takes the average as argument and returns the grade (A,B,C,D, or F) using standard grading.
• A function that prints each data member of the structure on a separate line and calls another function that prints the message You Passed, if average is >= 70, or You Failed.

Using a class:

You are to write a program that will define a class consisting of the following data members:

• Name - a string
• Student id number an integer.
• Three test scores positive short integers.

Input to the program consists of:

• name
• id number
• three test scores

Requirements:

• Must use a project with three files (a specification, an implementation, and a client file)
• Must define a null destructor, and a constructor with default arguments to initialize data members to null or zero.
• Use setter function(s) to read the name, id number and three test scores from the keyboard.
• Getter function(s) that prints each data member of the object on a separate line and uses two private functions that will find the average and grade (local to print) to be printed. Print will also print You Passed, if the average is >= 70 or You Failed.
• All getter functions are constant and all setter functions use constant parameters by reference.

Your output, for both, should be a report like follows:

Employee Name : Jim Donavan

Id Number : 2345

Tests :

1. 78
2. 88
3. 98

Average : 88.00

Grade : B You Passed.
