I think the answer is a no but want to confirm it.
What I'm looking to do is create a function that can return a string OR an int.
psudo code:
If it is possible what would I put before the function()? I know for int its int function() and for a string char* function().Code:function (int selector) { switch (selector) { case 0: <blah blah blah> return ("IAmAString"); case 1: <more blah blah blah> return (SomeInt); } }
Thanks
AFAIK, the only way to pass strings among the functions is to use structures or external variables.

Here is a working function to show you how to pass strings between functions. Only global variable is player.status.Originally posted by cc0d3r

This works and compiles without any warnings or errors.Code:char* titles (void) { switch (player.status) { case 0: return ("Dirt Ball"); break; case 1: return ("Serf"); break; case 2: return ("Peasant"); break; case 3: return ("Adventurer"); break; case 4: return ("Governer"); break; case 5: return ("Grand Governer"); break; case 6: return ("Duke"); break; case 7: return ("King"); break; } }
BTW what the heck is AFAIK?

Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah
You. Fetch me my copy of the Wall Street Journal. You two, fight to the death - Stewie
Ah.
Guess I will have to find another way this.
This is a bit of a guess, but might this be anything like what you're after?Code:#include <stdio.h> char *get_title(size_t selector) { static const char *title[] = { "Dirt Ball", "Serf", "Peasant", "Adventurer", "Governer", "Grand Governer", "Duke", "King", }; if ( selector < sizeof(title)/sizeof(*title) ) { return title[selector]; } return NULL; } int main ( void ) { size_t i; for ( i = 0; i < 10; ++i ) { char *mytitle = get_title(i); printf("%lu - ", (long unsigned)i); puts(mytitle ? mytitle : "invalid"); } return 0; } /* my output 0 - Dirt Ball 1 - Serf 2 - Peasant 3 - Adventurer 4 - Governer 5 - Grand Governer 6 - Duke 7 - King 8 - invalid 9 - invalid */
7. It is easier to write an incorrect program than understand a correct one.
40. There are two ways to write error-free programs; only the third one works.*
@ Dave_Sinkula - that code was an example for cc0d3r to show how you can pass strings.
@ Salem I think I understand what you did. Thanks for the answer. Will have to play with it to get down.
couldn't you just return a pointer to an int, and just typecase it, kind of like this
What will happen with that code, if it will even compile.Code:int *function(int showint) { if(showint) return 2; else return "hi"; } int main(void) { char hi[5]; int hello; hi = (char *)function(0); hello = (int *)function(1); return 0; }
Get rid of the red comma from Dave's post.Code:static const char *title[] = { "Dirt Ball", "Serf", "Peasant", "Adventurer", "Governer", "Grand Governer", "Duke", "King", };
Away.
It makes no difference. You can have a trailing comma. It has no effect.Originally posted by blackrat364

Quzah.
Hope is the first step on the road to disappointment.
Salem's idea is the best IMO and was the one I was thinking of.
Using a struct with a union and an indicator would be the easiest way.
