eatnumber1 / good.c
Last active August 29, 2015 14:09
The result of a challenge to write in C code that will do the following when run in Python: "good " * 2. I think I got a little carried away.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(void) {
for (char *s = "good ", l = strlen(s), z = 2 * l, d[z], *p = d; p == d + z ? *--p = 0, !puts(d) : 1; p = memcpy(p, s, l) + l);

int main(void) {
int wins = 2;
char *s = "good ";
char *p = malloc(wins * strlen(s) + 1);
for (int i = 0; i < wins; i++) p = strcat(p, s);
printf("%s\n", p);
