I need to create q&a project and I don't know how to handle scores when user gets the correct answer please help.

Question

For example
<p>what's the color of an orange?</p>
<label>Orange<input type="checkbox">< /label>
<label>white<input type="checkbox">< /label>
<label>green<input type="checkbox">< /label>
<label>blue<input type="checkbox">< /label>

Answer 1

make two variables like correct_answer and wrong_answer, declare those two to 0.
use an if-else statement to check whether the answer correct or not, if the answer is correct, then update the value by 1, like correct_answer += 1 and the same as wrong answer.

kinda like how I did it in https://www.github.com/Rellotscrewdriver/Math-Loop-Quiz-Program/tree/master/main.cpp (check line 11, 12, 78 and 81)
