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.
