C++ Data Persistance Help

Redo the code below to make the data persistent. You will have to save information in a file or files so that the application will pick up previously stored data and still operate as intended in Lab1 to

Write a program that allows the user to initially enter information on 4 students and 10 courses. Have the program associate each student to at least four courses for a semester session. The program will display a report showing the assigned courses for each students with the total number of credits.

The student information should include:

1. student ID

2. first name

3. last name

The course information should include:

1. Course ID

2. Course name

3. Number of credits

Design requirement:

A student will be assigned a course through a session. The session should include the following attributes:

1. session ID

2. student ID

3. course ID

4. start date

5. end date

.
