Syntax errors are caught by the compiler, and run-time errors are caught when your program is running. What are undetected errors? How do we catch them?

The syntax and run-time error are the types of the errors in the programming language. There is also some type of undetected errors in the programming language and the overall probability of the undetectable errors are basically used for the error detection and correction in the computer system.

The undetectable errors are basically undetectable and unidentified by the computer system and naked eyes. So that is why we use various types of technique for finding these types of error in the programming language. We using the CRC code technique for finding the undetectable errors in the programming language.
