Write a program that allows the user to create and maintain a list of contacts in a file contact will have a name and a phone number. In the file, each line should have a con phone number you may assume that ev single word (i.e. no last names) For example, if your file has two contacts in it, it might look something like this: Bob 555-1234 Jill 555-4321 Recall that if you try to open a file for reading before it exists, the program will crash.

C++ Question:

See Attached picture. Follow all instructions. Please create the code yourself. Thanks!!!

Write a program that allows the user to create and maintain a list of contacts in a file named MyContacts.txt. Each contact will have a name and a phone number. In the file, each line should have a contact's name followed by their phone number you may assume that every contact's name will just be a single word (i.e. no last names) For example, if your file has two contacts in it, it might look something like this: Bob 555-1234 Jill 555-4321 Recall that if you try to open a file for reading before it exists, the program will crash. Therefore, assume the user will fırst try to add a contact as their first option (i.e. I won't try to print the list or print a number first when l'm testing your code). In the addContact method, when you open a file for appending, it will be created for you. In a while loop, continually ask the user what option they would like to choose. Each option (other than the quit option) should call a function which performs a specific task. Their options are: 1. Call a function named printList: This function should print out the data in MyContacts.txt in the following way: Contact 1: Bob Phone Number: 555-1234 Contact 2: Jill Phone Number: 555-4321 etc.. 2. Call a function named findNumber which will find the phone number of a specific contact by asking the user enter a name. If the name is found in MyContacts.txt, return its corresponding phone number. Otherwise, return the empty string (quote-quote). Back in main, if a number is returned from findNumber, print it out. If the empty string is returned, tell the user the contact doesn't exit. 3. Call a function named addContact which will allow the user to add a contact to the file. In this function, ask the user to enter a name and phone number and then append these values to the end of MyContacts.txt. Again, you may assume that the user will only enter single-word names. 4. Quit the program
