Array of function pointers?

#include <stdio.h> void SayHello () { printf ("Hello.\n"); } int main (void) { void (*pFunctions [10]) (); pFunctions[0] = SayHello; pFunctions[0] (); return 1; }

Yeah I''ve done it.

In my application it turned out to be a bit of a wasted effort though. I was writing a 6502 processor emulator, and I thought it would be a lot faster to use an array of function pointers instead of a huge switch statement.

Turns out Visual C++ turns huge switch statements into jump tables.

You can use a function pointer (type void*) as you would any other pointer variable. RabidOcelot couldn''t have put it better (even told you how to do it)
siaspete: I wrote a command parser for a text adventure using a ternary search tree with a function pointer at each "found" node. Talk about a wasted effort- 11mos followed by segmentation faults I couldn''t trace, followed by hard drive failure where I lost everything. :~(

from siaspete:
"Turns out Visual C++ turns huge switch statements into jump tables"

Does any other compiler do that, such as the free borland
compiler which I use?

Is there a speed difference between an array of function
pointers and a switch statement?
I''m making either an interpreter or a custom script for
my game(I can''t tell the difference between the two).
