Question

So pretty much I need my code without the arrays, or lists. Please and thank you!

Important: You may not use arrays, lists, or similar for your questions. This will be covered in the next module. The objective is to use conditionals in order to achieve the overall task.

Checkpoint 3 is a continuation of the “Quiz” Programming Project.

This module week, you will implement repetitive tasks in your program while using conditional and iteration statements in C#.

• Implement a loop option that suits your project. The goal is to cycle through all questions in a first round and read the appropriate user’s input from the console.
• Mark whether the input is the correct answer.
• Cycle through all incorrectly answered questions in a second round.
• Tally the results and display the number of correct/incorrect answered questions, at the end.
• Test the code for different input values of the variable(s) including out-of-range values and adding a statement displaying an error message.
• Document a successful run of the program.

Note:-

I assume you want to avoid all arrays and change into conditional statements.Any queries let me know
