Question
Must compile on Visual studio 2015 Goals (Requirements) - No Change The program will help a student to submit a homework assignment as a text file. The file should contain the name of the assignment, name of the student and the actual content of the assignment as multiline text. The teacher should be able to open the submitted file and assign a numerical score to it A new file should then be created and saved that contains the name of the assignment name of the student, the score of the assignment followed by the content of the assignment. Student should be able to see the graded assignment Development Strategy (Removed from Project 3, moved to Project4) 1. We will split the code into .h and.c files 2. We will learn how to build two application from a single common code. Phase 1: 1. Split the code into two assignmentgrading3.h, assignmentgrading3.c like illustrated in the class. Phase 2: 2. Create two applications, one for student and the other for teacher. Your student and teacher applications must be fully functional. Ask for help if you are confused Bonus [10 points]: Deliver a library for assignmentgrading.h with proper README.txt file.Explanation / Answer
