A logic error produces unintended or undesired output or other behaviour, although it may not immediately be recognized as such.https://en.wikipedia.org › wiki › Logic_errorLogic error – Wikipedia is a problem with a computer’s programming code that is not readily identified when the code is written or compiled.

What is logical and syntax error?

A syntax error occurs when we make a mistake in our coding, such as forgetting a semicolon to indicate the end of a statement. A logic error is harder to find. This occurs when we have all the correct syntax but we coded a portion of the program with an error, such as maybe, divide by zero.

What is a syntax error?

What is logical error example in C?
