|(programming)||switch statement - (Or case statement, multi-way branch) A
construct found in most high-level languages for selecting
one of several possible blocks of code or branch destinations
depending on the value of an expression. An example in C is|
switch (foo(x, y)) case 1: printf
The break statements cause execution to continue after the whole switch statemetnt. The lack of a break statement after the first case means that execution will fall through into the second case. Since this is a common programming error you should add a comment if it is intentional.
If none of the explicit cases matches the expression value then the (optional) default case is taken.
A similar construct in some functional languages returns the value of one of several expressions selected according to the value of the first expression. A distant relation to the modern switch statement is Fortran's computed goto.
