Split a String Using Delimiter

Code

#include <stdio.h>
#include <stdint.h>

void split_string(const char *str, char delimiter, char tokens[10][20], uint8_t *count) {
    char *p0 = (char *)str;
    char *p1 = (char *)str;
    *count = 0;
    do {
        if ((*p1 == delimiter) || (*p1 == '\0')) {
            char *tgt = tokens[(*count)++];
            int len = 0;
            while ((p0 < p1) && (len++ < (20 - 1))) {
                *tgt++ = *p0++;
            }
            *tgt = '\0';
            p0++;
        }
    } while (*p1++);
}

int main() {
    char str[101];
    char delimiter;
    fgets(str, sizeof(str), stdin);
    scanf(" %c", &delimiter);

    // Remove newline
    uint8_t i = 0;
    while (str[i]) {
        if (str[i] == '\n') { str[i] = '\0'; break; }
        i++;
    }

    char tokens[10][20];
    uint8_t count = 0;

    split_string(str, delimiter, tokens, &count);

    for (uint8_t i = 0; i < count; i++) {
        printf("%s\n", tokens[i]);
    }

    return 0;
}
