Go (also known as Golang) is one of the most popular languages today and is a key part of many enterprise tech stacks. Because Go's memory management architecture makes concurrency easier, many developers prefer it over traditional languages.

In this course, you will learn the core constructs and techniques of Go as well as advanced concepts of the language. In particular, you’ll learn how to program efficiently by becoming aware of the pitfalls and patterns that are commonly encountered in Go and by building your own applications.

Once you’ve completed this course, you will be able to write concurrent programs and improve the performance of existing ones, thus creating a more robust experience for everyone. Concurrency is in high demand today since it enables developers to reduce execution time of applications significantly, and Golang provides a very rich support for achieving this.

# Problem statement

Write a quiz that will time out after a time limit determined by you. The quiz will read the questions and answers from the CSV file. After the timer ends, the quiz should display the number of correct answers out of the total number of questions.

For example, within 30 seconds and out of 10 questions, if the user gives three correct and two incorrect answers, the final statement should look like this:

```txt
Correct: 3, Incorrect: 2, Total: 10
``` 

Follow these steps:
- Create a `struct` that stores the question and answer.
- Create a function that reads the CSV file.
- Create a function that stores data in a `struct` array and reads from it.
- Create a timer for the timeout using `select`.
- Use loops to loop over the problems array, ask user input for each problem, and store results in variables.
- Make sure the timeout occurs after the given time limit.
- Create a file that contains questions and answers separated by a comma, and store it in the CSV file.

If you want to proceed without creating a `struct`, that will also work fine.
