hello, I am trying to learn c++, and I am trying to run this program to display the correct answers in the end. the user will be asked to input their answers to the 20 questions on the list.
for what I have read, I think I should be using some if or nested if statements? please help, thank you. Also, this is not my assignment (as I was accused of from other forum I tried), I am already working and just trying to learn programming on my spare time. thanks again, code is below.

#include <conio.h>
#define p printf
#define s scanf
