Question

Write a C# program that has a method named ReadArray. In this method, ask the user to enter names of employees, the program stops taking new names when the user enters the word “quit”. All names must be stored in an array as the user enters them; name the array, empNames. In the ReadArray, call another method named ReverseArray and pass to it, the empNames. The ReverseArray method will reverse the content of empNames. In ReadArray, print the reversed array. In the main method, only call the ReadArray, without passing anything to it. You should demo the pass-by-reference in this question.

Sample run:

Please enter an employee name: Karein

Please enter an employee name: James

Please enter an employee name: Komal

Please enter an employee name: Rohit

Please enter an employee name: quit

 

The names are:

Rohit

Komal

James

Karen
