gcc: stdio.h: No such file or directory

UPDATE: Well... adding g++ helped :P. For any developers reading this, consider including the libraries when someone adds gcc. I had *no idea* that I needed to add g++ as well. Oh well.

Hi! Installation went pretty smoothly. Just a tiny hiccup with gcc I guess. After "apk add gcc" I decided to compile a little hello world program and, well, like it says on the tin. I thought the standard libraries and dependencies would be added along with gcc. I'm not sure what else to add, I mean musl is already installed. What am I missing? Sorry if I am a bit of a noob-head.

#include <stdio.h>
#include <stdlib.h>
 
int main()
{
        printf("Hello.");
        exit(0);
}
