c++

Create a program that manages a list of active users on a system. This could be an on-line game, web site, etc.

This program should use Vectors instead of Arrays. If you use a FOR loop - use the Range-Based for loop ( pg 433 8th Ed - pg 439 9th Ed)

The program needs to provide a menu with the following options with working code to do these options:

1. Add a userName

2. List all userNames

3. Delete a userName

X. Exit.

Any invalid input for the menu will simply redisplay the menu.

Option 1 will prompt for a userName. An empty name will be ignored. The name will be added to the vector and the program menu is shown.

Option 2 will List all the users and their associated index. I.E

The index number given for input needs to be tested to be within the range of possible values The deleting syntax is not covered in Chapter 7. There are at least 2 ways it can be done. 1. Assign the last entry to the element to be deleted, then issue a pop_back to remove the last entry. 2. Use the erase member function. This is listed in table 16-6 page 1012 - 8th edition or table 17-8 page 1041 9th edition. If "users" is the vector name, the syntax for using erase would be users.erase(users.begin() + indexToDelete); Option X should delete all entries in the vector and exit the program. See table 7-4 for the best Member function to do that.
