1 definition found From The Jargon File (version 4.4.7, 29 Dec 2003) [jargon]: gotcha n. A misfeature of a system, especially a programming language or environment, that tends to breed bugs or mistakes because it is both enticingly easy to invoke and completely unexpected and/or unreasonable in its outcome. For example, a classic gotcha in C is the fact that if (a=b) code; is syntactically valid and sometimes even correct. It puts the value of b into a and then executes code if a is non-zero. What the programmer probably meant was if (a==b) code;, which executes code if a and b are equal.
