I have this test code for the game programming library allegro.
Code: #include <allegro.h>
#include <stdio.h>
int i;
int main()
{
allegro_init();
set_gfx_mode(GFX_AUTODETECT, 640, 480, 0, 0);
printf("Hello World");
for i<10000;
{
i++;
}
return 0;
}
END_OF_MAIN()
When ran I get a syntax error about the i variable. plz help.
You never declare it. You need to do int i;.
EDIT: Wait, I see it at the top there, I missed it. You'll want to give it an initial value, though. It's for for loop. for(<initialization>; <condition>; <increment>) { ... } so:
Code:
for (i = 0; i < 1000; i++) { ... }
To implement a delay in Allegro you may wish to look at its
timer functions; that loop will run incredibly quickly, and an optimising compiler should replace it with
i = 10000; in any case.

Quick tip: don't make variables global unless you have a good reason to (i.e. put the "int i;" statement in main.)
