A Error is a kind of oversight. We can say a mistake is a state of having wrong or false information or a lapse is characterized as a surprising, invalid project state from which it is difficult to recuperate. 

Error can likewise be characterized as "a deviation from exactness or accuracy". A "slip-up" is a blunder brought about by a blame: the issue being confusion, heedlessness, or absent mindedness. A lapse message with filename, line number and a message depicting the slip is sent to the program.
