What is a logic error called?
A logic error is a problem with a computer's programming code that is not readily identified when the code is written or compiled. Sometimes called a semantic error, a logic error generally is the programmer's fault; even if the coding is correct, the resulting answer might yet be incorrect.
How do you find logic errors?
To find logical errors, read through your program line by line and try to relate what each line is doing to the behavior you're seeing in your project. The LilyPad does exactly what your program tells it to do. Your job is to find the mismatch between what you want it to do and what the program is telling it to do.
