Finals Urgent!
can anyone help me out? this is my final project and i need to know how to do part 2.
Create a menu driven program to simulate a simple database system. The program will open a file and reads the data and store them in an array of objects to represent the students’ information as it was created in the first part. The format and a sample of the file are provided above. If you are using arrays make the size 20 and if there are more students in the file print a message and only process the 20 that are stored in the array. Assume some of the data stored in the file are incorrect, need to verify the data.
Implement the following menu:
'O' -- Open an existing student’s file.
'A' -- Add new person to the current list.
'R' -- Remove a person from the current list.
'P' -- Print one student’s info in the current list.
'E' -- Edit information for 1person.
'S' -- Search.
'T'-- Sort the list
'X'-- Exit the program.
COMMENTS :
For O : Prompt the user for the file name, then open it.
Finally, read the entire file into the list and update the number of elements read.
For A : Add info for a new student if there is space in the list and the student is not on the list.
For R : Remove a student from the list. (Prompt user for last name)
For P : Show a sub-menu
L: Print all students’ information in the list with a page format to the monitor (refer to sample)
T : Print all students’ information in the list in a table format to the monitor(refer to sample)
F : Print in a table format to a file. Format is the same as T above.
For E: Prompt the user for the person’s last name. If name not found, print person not found message
and return to main menu. If found provide a sub-menu and allow user to change any data necessary except name.
For S: Prompt the user for the person last name. If name not found, print person not found message
and return to main menu, else return the index of the record.
For T : Sort list, display a sub-menu:
‘N’ : Sort on names (alphabetical).
‘C’ : Sort on GPA (high to low descending).
For X : Make sure to save the list information to the disk. Print an ending message. Then halt the program.

Requirements:
I. Include all the necessary structure definition and utility functions you may need for the structure.
II. Driver program must be modular, use as many functions as possible.
III. Must use arrays or vectors to store a list of students in the program.
IV. You may assume there are no more than 20 students in the file, (check for overflow).
V. You may assume all names in the data file are unique, no duplicates are allowed in the list.
VI. You may use any platform to develop the program, but make sure it compiles and run on Visual Studios before submitting it.
VII. Make sure the program is user friendly.
Suggestions:
1) Start with an overall design, students list, and options (does not need to be detailed)
2) Design you structure for student info, and then implement the structure, utility functions and a small main driver to test the structure.
a. Make sure you have all the necessary structure utility functions:
i. Read
ii. Print
iii. Process functions
3) Create a list of students and start implementing the menu options one by one and test them as you go using the small main test driver.
a. Open file
b. Read into the list
c. Print the list
d. Process a person (add, edit, remove,…)
e. Search list
f. Sort list
4) Develop a menu function
5) Make the final main function
basically I have done up to creating menu part 'A' which is addingperson I need to know how to remove a person and so on. A great help would be appreciated!
