Is it possible to store the address of a label in a variable and use goto to jump to it?

by

The C and C++ standards do not support this feature.

However, the GNU Compiler Collection (GCC) includes a non-standard extension for doing this, as described in the Labels as Values section of the Using the GNU Compiler Collection manual.

Essentially, they have added a special unary operator && that reports the address of the label as type void *. See the article for details. With that extension, you could just use && instead of & in your example, and it would work on GCC.

P.S. I know you don’t want me to say it, but I’ll say it anyway… DON’T DO THAT!!!
