In this module you learned about searching, sorting and algorithms in C++ and how to implement these elements in your C++ programs. In this assignment you will implement your knowledge of searching, sorting and algorithms for charge account validation system. Write a program that lets the user enter a charge account number. Be sure to include comments throughout your code where appropriate. The program should determine if the number is valid by checking for it in the following list of valid account numbers:

Then use a simple linear search to locate the number entered by the user. If the user enters a number that is in the array, the program should display a message indicating that the account number is valid. If the user enters a number not in the array, the program should display a message indicating it is invalid. Next, using the same one-dimensional array, use a bubble-sort to put the array in order and perform a binary search to locate the number entered by the user. If the user enters a number that is in the array, the program should display a message indicating that the account number is valid. If the user enters a number not in the array, the program should display a message indicating it is invalid.

Question is not well presented:

The search strings in the question are not well formatted.

First thing, I'll arrange the account number in order of 7;

Meaning that the length of each account number is 7
