[Solved] How to increment an IP address in a loop? [C] [closed]

by


A naive implementation (no inet_pton) would user 4 numbers and print them into a char array

#include <stdio.h>

int inc_ip(int * val) {
    if (*val == 255) {
        (*val) = 0;
        return 1;
    }
    else {
        (*val)++;
        return 0;
    }
}   

int main() {
    int ip[4] = {0};
    char buf[16] = {0};

    while (ip[3] < 255) {
        int place = 0;
        while(place < 4 && inc_ip(&ip[place])) {
            place++;
        }
        snprintf(buf, 16, "%d.%d.%d.%d", ip[3],ip[2],ip[1],ip[0]);
        printf("%s\n", buf);
    }
}

*Edit: A new implementation inspired by alk

struct ip_parts {
    uint8_t vals[4];
};

union ip {
    uint32_t val;
    struct ip_parts parts;
};

int main() {
    union ip ip = {0};
    char buf[16] = {0};

    while (ip.parts.vals[3] < 255) {
        ip.val++;
        snprintf(buf, 16, "%d.%d.%d.%d", ip.parts.vals[3],ip.parts.vals[2],
                                        ip.parts.vals[1],ip.parts.vals[0]);
        printf("%s\n", buf);
    }
}
