function. could someone pls give a simple example of its use, which ive heard is sort of like this:

hi,

If your question is about use of goto, probably
this may be enough


printf( "1\n" ) ;
printf( "2\n" ) ;
goto mylabel ;

printf( "3\n" ) ;
printf( "4\n" ) ;

mylabel:
printf( "5\n" ) ;


Probably in your examples the label was named "end" that
is not a keyword in C.


Many people dislike use of goto, but this is a storic problem.
In years '70 language as BASIC, FORTRAN required use
of goto.

When languages as: PASCAL, new version of BASIC, FORTRAN,
came out, the purists sayd that goto was to forget.

I think is bad the abuse of it, but using it rarely and
in particular situations, may give to your program
a better read-bility.

However remeber that in C there are also statement as:

break, continue, return: you must use them before use goto.

In PASCAL such statements are not, and if you want avoid
big if 3 pages long, a "goto end" is required.
