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
    int i = 0, j = 0, k = 0;
    *count = 0;

    while (str[i] != '\0') {
        // If delimiter found → end current token
        if (str[i] == delimiter) {
            if (j > 0) { // avoid empty tokens
                tokens[k][j] = '\0';
                k++;
                j = 0;
            }
        } else {
            if (j < 19) { // prevent overflow
                tokens[k][j++] = str[i];
            }
        }
        i++;
    }
     if (j > 0) {
        tokens[k][j] = '\0';
        k++;
    }

    *count = k;
}

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;
}
