Why Go takes 30 seconds and C just 0.2 ?

benchmark.c

#include <stdio.h>

#define MIN 1
#define MAX 1000001

int main (int argc, char **argv) {
        for (int secret = MIN; secret <= MAX-1; secret++) {
                printf("%d", secret);

                int max = MAX;
                while(1) {
                        int guess = (min + max) / 2;
                        if (guess < secret) {
                                printf("<");
