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) {
    *count = 0;  // ✅ Initialize count at the start

    for (int i = 0; i < 10 && *str; i++) {  // outer loop over tokens
        int j = 0;
        while (j < 19 && *str && *str != delimiter) {  // inner loop over characters
            tokens[i][j] = *str;  // copy character
            str++;
            j++;
        }
        tokens[i][j] = '\0';  // ✅ null-terminate the token

        (*count)++;  // ✅ increment token count only after finishing a token

        if (*str == delimiter) {
            str++;  // ✅ skip the delimiter
        }

        if (*str == '\0') {
            break;  // ✅ stop if end of string
        }
    }
}
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;
}
