HOW TO MAKE A TRUE OR FALSE QUIZ USING HTML, JAVASCRIPT, AND CSS

This code is going to be almost similar to the other quizzes codes, but with some changes. Some of these changes may be easier for the programmer to use. The quiz has 10 questions.

The true or false quiz is going to be only 2 options for each question. The differences are in the functions. The first code is going to show you how you can use only 2 functions for "Correct" and "Incorrect". That is, if you don't want to add any details for each correct or incorrect answer, which "Correct" and "Incorrect" will work for all questions. Remember, for both codes you can still change the letter "c" and "i" in the functions "q1c" and "q1i", but make sure you write the correct answer for the "c" and incorrect answer for "i".

If you want to watch the video and see how it is done, you can check it out below.

The following code is the same as the one above, but the changes made were for the "correct" and "incorrect" answers if you want to add a detailed message to each answer. The code will be longer and some changes have to be made as well. This time instead of having "q1c" and "q1i" for all answers, they must change to "q1c", "q2c", "q3c", etc. And "q1i", "q2i", "q3i", etc. Functions are going to be added as well. I colored the changes in a light brown color, and green for the detailed messages.
