/pres@dens los'@j/ , n. [C programmers] Coding error in an expression due to
|
|
|
|
unexpected grouping of arithmetic or logical operators by the compiler. Used
|
|
|
|
esp. of certain common coding errors in C due to the nonintuitively low
|
|
|
|
precedence levels of , | , ^ , , and (for this reason, experienced C
|
|
|
|
programmers deliberately forget the language's baroque precedence hierarchy
|
|
|
|
and parenthesize defensively). Can always be avoided by suitable use of
|
|
|
|
parentheses. LISP fans enjoy pointing out that this can't happen in their
|
|
|
|
favorite language, which eschews precedence entirely, requiring one to use
|
|
|
|
explicit parentheses everywhere. See aliasing bug , memory leak , memory
