Statements
The goto Statement
The goto Statement
The goto statement transfers control to a labeled statement that is within the scope of the
current function.
Syntax
goto identifier ;
Description
The goto statement causes an unconditional branch to the named label in the current
function. Because you can use goto statements to jump to any statement that can be
labeled, the potential for their abuse is great. For example, you can branch into loop bodies
and enter blocks at points other than the head of the block. This can cause problems if you
attempt to access variables initialized at the beginning of the block. Generally, you should
avoid using goto statements because they disturb the structure of the program, making it
difficult to understand. A common use of goto statements in C is to exit from several levels
of nested blocks when detecting an error.
