Re: getting variables in order


Used an array instead. I do not know what is your machine, so you should
use sizeof o ensure portability, but I'll assume 1 byte chars and 4 byte
integers:

char variables[17];
char *a = &variables[0];
char *b = &variables[1];
int  *c = &variables[2];
char *d = &variables[6];
char *e = &variables[7];
int  *f = &variables[12];
char *g = &variables[16];
