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) {
  int i = 0;
  while (*str != '\0') {
    // if delimiter, increment count, then start new array
    if (*str == delimiter) {
      tokens[*count][i] = '\0';
      (*count)++;
      i = 0;
      str++;
    } else {  // fill in each inner array with cmd
      tokens[*count][i] = *str;
      i++;
      str++;
    }
  }
  // last edge case
  tokens[*count][i] = '\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;
}
