Students ProgrammingAssignment6

   Project Goals
The goal of this project is to:
1.    Allow students to create a program which uses **File IO**.
    Important Notes:
1.    **Comments**: Header comments are required on all files and recommended for the rest of the program. Points will be deducted if no header comments are included.
2.  **Filename**: Save your program as ```students.c```.
   Program
Write a program for managing students which loads student information for one student from a file and displays the data, or allows the user to overwrite the file with a new student's information. The user should be shown a menu with three options: display student, add student, or exit the program. 

If the user chooses to exit, the program should end. 

If the user chooses to display the student, the contents of the students.txt file should be loaded and displayed to the screen. If the file is not available, an error message should be displayed to the user.

If the user chooses to add students, they should be prompted for the student number, student standing, and student GPA. Each of the new items should be added to the students.txt file. If the file is not available, an error message should be displayed to the user.

    The example executable:
An example executable is provided in this repository. You should be able to run it from your project folder.
If you encounter a "permission denied" error when attempting to run the executable, type ```chmod u+x studentExecutable``` into the terminal and try running the executable again.
   File Format
The input file should be in the following format (each item separated by a space):  
Number Standing GPA

The following is an example file:
```
431 S 2.4000
```
The following is an example file AFTER the user adds a student: 
```
42 F 1.2000
```
   Requirements
*main()*  
**Functionality**: This main function should prompt the user for a menu option. It should decide, based on that menu option which actions to perform. Option 0 ends the program. Option 1 opens the students.txt file for reading and checks for a successful connection to the file stream. If it can, it will display the student data then close the file. Option 2 opens the students.txt for writing and checks for a successful connection to the file stream. If it can, it gets a new student, then closes the file. Any other options should result in an error message.  

In addition to the main functions, your program should have 3 more functions:  

*getMenuChoice()*  
**Input Parameters**: none  
**Returned Output**: int  
**Functionality**: This function should display to the screen the options available to the user, get the user choice, and return the users inputted menu choice to the calling function. 

*displayStudent()*  
**Input Parameters**: FILE pointer  
**Returned Output**: none  
**Functionality**: This function should accept a file pointer which has already been connected to a file stream. It should read in the student data and display it to the screen.  

*saveStudent()*  
**Input Parameters**: FILE pointer  
**Returned Output**: none  
**Functionality**: This function should accept a file pointer which has already been connected to a file stream. The user should be prompted for the student number, number of credits, and student GPA, which should all be saved to the file.  

   Submission details
To submit your project, you will have to use git on your VirtualBox installation:

2.    Type 
```git clone clone_URL```
3.    cd into your new assignment directory
4.    After working on your files
5.    When you’re ready, type the following commands:

   Academic Honesty
Academic dishonesty is against university as well as the system community standards. Academic dishonesty includes, but is not limited to, the following:
Plagiarism: defined as submitting the language, ideas, thoughts or work of another as one's own; or assisting in the act of plagiarism by allowing one's work to be used in this fashion.
Cheating: defined as (1) obtaining or providing unauthorized information during an examination through verbal, visual or unauthorized use of books, notes, text and other materials; (2) obtaining or providing information concerning all or part of an examination prior to that examination; (3) taking an examination for another student, or arranging for another person to take an exam in one's place; (4) altering or changing test answers after submittal for grading, grades after grades have been awarded, or other academic records once these are official.
Cheating, plagiarism or otherwise obtaining grades under false pretenses constitute academic
dishonesty according to the code of this university. Academic dishonesty will not be tolerated and
penalties can include cancelling a student’s enrolment without a grade, giving an F for the course, or for the assignment. For more details, see the University of Nevada, Reno General Catalog.
