Homebrew am i missing something?

[redact]

so i recently started doing a course to learn c++ (as well as java and some other stuff)
and i thought maybe i could practice by doing some ds dev...

i started fooling around with the hello world that came with the examples

Spoiler: originally something like this

CODE#include
#include

int main(void)
{
ÂÂÂÂint i;

ÂÂÂÂconsoleDemoInit();

ÂÂÂÂvideoSetMode(MODE_FB0);

ÂÂÂÂvramSetBankA(VRAM_A_LCD);

ÂÂÂÂprintf("Hello World!\n");
ÂÂÂÂprintf("www.Drunkencoders.com");

ÂÂÂÂfor(i = 0; i < 256 * 192; i++)
ÂÂÂÂÂÂÂÂVRAM_A = RGB15(31,0,0);

ÂÂÂÂreturn 0;
}

and after fiddling a bit i got some sexy patterns happening

Spoiler: sexy pattern

CODE#include //libnds
#include //standard input/output

int main(void)
{
ÂÂÂÂint i;

ÂÂÂÂconsoleDemoInit();

ÂÂÂÂvideoSetMode(MODE_FB0);

ÂÂÂÂvramSetBankA(VRAM_A_LCD);

ÂÂÂÂprintf("COLORS!\n");

ÂÂÂÂfor(i = 0; i < 256 * 192; i++)
ÂÂÂÂÂÂÂÂVRAM_A = RGB15((0),(i%257/2),(i%255/2));

ÂÂÂÂreturn 0;
}

both of these code snippets will compile and run perfectly fine. if, however i edit the code slightly...

Spoiler: it breaks

CODE#include //libnds
#include //standard input/output

int main(void)
{
ÂÂÂÂint i;
ÂÂÂÂint r, g, b;

ÂÂÂÂconsoleDemoInit();

ÂÂÂÂvideoSetMode(MODE_FB0);

ÂÂÂÂvramSetBankA(VRAM_A_LCD);

ÂÂÂÂprintf("COLORS!\n");

ÂÂÂÂfor(i = 0; i < 256 * 192; i++)
ÂÂÂÂÂÂÂÂr=0;
ÂÂÂÂÂÂÂÂg=(i%257/2);
ÂÂÂÂÂÂÂÂb=(i%255/2);
ÂÂÂÂÂÂÂÂVRAM_A = RGB15(r,g,b);

ÂÂÂÂreturn 0;
}

other info:
IDE: programmers notepad (was already pre-configured for libnds on installation of dkp)

You forgot to add braces to the for-loop code block:

CODEÂÂÂÂfor(i = 0; i < 256 * 192; i++)
ÂÂÂÂ{
ÂÂÂÂÂÂÂÂr=0;
ÂÂÂÂÂÂÂÂg=(i%257/2);
ÂÂÂÂÂÂÂÂb=(i%255/2);
ÂÂÂÂÂÂÂÂVRAM_A = RGB15(r,g,b);
ÂÂÂÂ}

of course, i knew i was missing something
thanks man

edit: congrats on your first post
