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) {
    // Your logic here
    *count = 0;
    const char *i = str;
    while(*i != '\0') {
        // printf("i: %c\n",*i);
        if (*i != delimiter) {
            i++;
            continue;
        }
        int j = 0;
        while(str != i) {
            // printf("\tstr: %c\n",*str);
            tokens[*count][j++] = *str;
            str++;
        }
        tokens[*count][j] = '\0';
        // printf("\t\t- %s\n",tokens[*count]);
        (*count)++;
        i++;
        str = i;
    }
    int j = 0;
    while(str != i) {
        // printf("\tstr: %c\n",*str);
        tokens[*count][j++] = *str;
        str++;
    }
    tokens[*count][j] = '\0';
    (*count)++;
}

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;
}
