Please do the whole program in x$86$ MASM assembly with the Irvine library. You don't need to do the extra credit

Summary:

Create a simple Contact Management System using assembly language that allows a

user to add and display contacts. This assignment will exercise your skills with strings and

arrays in MASM. The system will support storing multiple contacts, where each contact has

a name and a phone number.

Note: The user must always be prompted for input, and all inputs must be thoroughly

error$-$checked.

Assignment Description

Menu Logic:

The main loop displays the menu and handles user input.

Based on the user's selection, it calls the appropriate functionality $($add contact,

display contacts, or exit$).$

Add Contact: Allows the user to input a contact's name $($up to $20$ characters$)$ and

phone number $($exactly $10$ characters$).$ A confirmation message of successfully

adding a record to the lists must be displayed.

Display All Contacts: Displays all stored contacts with their respective names and

phone numbers.

The main menu should be displayed each time the user completes a procedure,

allowing them to choose another option or exit the program.

Data Storage:

Contacts will be stored in an array of structures. Each structure contains:

Name: A string of up to $20$ characters plus a null terminator.

Phone Number: A string of $10$ characters $($assumed to be digits without

formatting$).$

Program Flow:

The program will present a menu with options to add a contact or display all

contacts.

The user can input up to $20$ contacts for simplicity.

Input validation: All inputs must be error$-$checked.

Ensure names are not longer than $20$ characters and phone numbers are

exactly $10$ characters without null terminator

Handle invalid menu inputs.

Prevent adding more than $5$ contacts.

Procedures and Stack Frame Usage:

Create at least two procedures that add contacts and display the contact list

For two procedures mentioned above, pass the parameters using the STACK. Ensure

the parameters are placed on the stack before calling a procedure.

You are not allowed to use 'Enter' and 'Leave' instructions, or LOCAL

directive.

You must access those parameters via EBP in each stack frame

Correctly setting up stack frame is the most important part of this assignment

Make thoughtful decisions on pass$-$by$-$value vs$.$ pass$-$by$-$reference parameters.

Uses offsets and multipliers to correctly access the array elements for each

contact.

Contacts List:

O$.$ John Doe $-1234567890$

Bob Smith $-8765432100$

Sung Nam $-3456789012$

Error checking and exception handling with proper messages:

Minimally, following two user input errors must be handled:

Menu option

The length of the phone number must be exactly $10$ digits, and it should

contain digits only, $\text{'}0\text{'}-\text{'}9\text{'}.$ The length can't be smaller than $10.$

Programming Style:

Style is a critical component of your grade. Include descriptive comment blocks

for all procedures, including main.

Capture the algorithm or program flow in the header of each function

Prohibited Constructs:

Do not use any directives to assist with program flow, such as $.$if$,.$while, $.$else,

etc.

The USES directive is also prohibited.

Testing

At least $7$ records must be added.

Displaying the list after adding $3^("$rd $"),5^("$th $"),$ and $7^("$th $")$ records showing the current

records at each display point

All exception cases must be tested and the exception must be handled

graciously. The results of invalid input cases must be included in output file for

full credit consideration.

See above for the minimal error checking cases.

You may record the result of all possible test cases in one shot of testing upon

completing each unit test first.

Example Interaction:

Add Contact:

Enter Name $($max $20$ chars$)$: John Doe

Enter Phone Number $(10$ digits$)$: $1234567890$

Contact added successfully.

Display All Contacts:
