Design a program that allows the user to enter 20 names into a String array. Sort the array in ascending (alphabetical) order and display its contents. do psuedocode in c++

I need help creating a C++ code. I need help writing a program that lets the user enter a charge account number. Then the program needs to determine if the number is valid by checking an array with these values.  5658845, 4520125, 7895122, 8777541, 8451277, 1302850, 8080152, 4562555, 5552012, 5050552, 7825877, 1250255, 1005231, 6545231, 3852085, 7576651, 7881200, 4581002 Then I just need a simple linear search to locate the numbers entered by the user. If the user enters a correct number it should display a message "valid" if not invalid.

Exercise 2  This exercise is designed to assess student’s skills of writing programs using arrays and loops. Write a C++ program using array and loop that prompts a user to enter 15 Students’ marks in ProgramDesign and Implementation (PDI) Module in an array. The program sorts the students’ marks in descending order using a loop and displays the marks of all students as well as lowest, highest, average marks, and the class result based on the average module marks. The result criteria is given below:Average is less than 40 = Poor ResultAverage is between 40 to 49 = Fair ResultAverage is less than 50 to 59= Good ResultAverage is less than 60 to 69 = Very Good ResultAverage is between 70 to 79 = Excellent ResultAverage is 80 or greater = Outstanding ResultNote: You must demonstrate the use of arrays and loops. Your code must be properly commented Sample Output:Welcome to Result Management SystemEnter PDI Marks of Student 1: 50Enter PDI Marks of Student 2: 35Enter PDI Marks of Student 3:…

A C-string variable is an array, so we can use index operator [ ] to access individual character. True or false?
