The Runtime Error can only be found when the program is successfully compiled and an error occurs. The Compile-time error, which I think is the most common, can be found when compiling.
So the program I posted yesterday has an error due to long codings. There were right answers in the final round where it displays Wrong, but the score is added.
Here's the final and error-free code. Try it for yourself.
