[Solved] C#, How to make and call functions

Question

First of all, your for loop at the end (the one which gave you an error). Contains a misspelled property. The

integer_array.length

should actually be

integer_array.Length

The ‘length’ property is ‘Length’ in C#

And for making sure that your code is looped until any of the correct input keys have been pressed.
You can encapsulate your whole code body with

while(true) {
// Your code here
}

And then make sure that at the very end; inside each if statement. You should add the keyword

break;

Except for the last one of course.

And last thing.
For seperating each if statement into their own functions, all you have to do is… (For example)

Change the following code

    else if (option == 2)
    {
        Console.Clear();
        Console.WriteLine("                                     ---  Random Number Generator  --- ");
        Console.WriteLine();
        Console.WriteLine();
        Console.WriteLine("                                                   Help Menu");
        Console.WriteLine();
        Console.WriteLine("To navigate through the program type in the number related to the task then press enter.For example To exit the program press 4 and then press enter.");
        Console.WriteLine();
        Console.WriteLine();
        Console.WriteLine("Press any key to Exit");
    }

Into

    else if (option == 2)
    {
        OpenHelpMenu();
    }

And then at the end of the file; before the last two closing brackets }
Add a new function

void OpenHelpMenu() {
  Console.Clear();
  Console.WriteLine("                                     ---  Random Number Generator  --- ");
  Console.WriteLine();
  Console.WriteLine();
  Console.WriteLine("                                                   Help Menu");
  Console.WriteLine();
  Console.WriteLine("To navigate through the program type in the number related to the task then press enter.For example To exit the program press 4 and then press enter.");
  Console.WriteLine();
  Console.WriteLine();
  Console.WriteLine("Press any key to Exit");
}

Repeat with each if statement and you should be fine 🙂
