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.
