My first C program

#include <stdio.h>

void f() { printf("hello, world\n"); }

char prog[6];
typedef void (*callable)();

int main() {
prog[0] = 0xe8;
*(int *)(prog+1) = ((char *)f)-((char *)(prog+5));
prog[5] = 0xc3;
((callable)prog)();
}


I wrote this last night after finishing K&R. How is it?

assigning an address to int
architecture dependent implementation

terrible!

The rich take advantage of the poor until the poor revolt and the rich find their heads under guillotines. A parasite that is eliminated by a collective action of their numerous hosts is not one fit for survival. Well adapted parasites are difficult to remove, like worms in the intestines of animals, or ticks on the hides of animals that don't have the dexterity to remove them.

wrong thread. I'm deeply embarrassed. So much so I will never post this shit on /prog/ again. Please hide your eyes from >>3.

your code is unportable and horrible, if L. A. was alive he would be deeply disapointed
