There is actually a goto in many languages, including C, C++ and I think Java, but if you
use goto in your C program, your colleagues are liable to
break your arms and knee-caps, knock out your teeth and poke out your eyes with a
corkscrew and actually get away with it on grounds of justifiable
self defence.
Well, if you read Kernighan & Ritchey's original "The C Programming
Language" book, the "goto" was only put in because C doesn't provide a
multi-level break statement. The only way out of that situation short
of lots and lots of sentinel values is a goto. Of course, they also
state that if you are more than four levels of indentation deep, you
probably should think about splitting out a function or rethinking your
logic.
There are times where a "goto" is appropriate, but one should try to
minimize its use--true in almost any procedural language. If you want
to abuse the "goto", write in BASIC. :-)
