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
    char* current_str = &tokens[0][0];
    uint8_t word_num = 0;
    uint8_t i=0;
    while(*str!='\0'){
        // if delimiter advance current str pointer to next line
        if(*str==delimiter){
            word_num++;
            char* current_str = &tokens[word_num][0];
            i=0;
            str++;
        }
        // copy char to current str
        // current_str[i] = str[i];
        tokens[word_num][i] = *str;
        str++;
        i++;
    }
    *count = word_num+1;

}

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;
}
