Split a String Using Delimiter

Dont store beyond maximum no of columns

#include <stdio.h>
#include <stdint.h>

#define MAX_COL 20  

void split_string(const char *str, char delimiter, char tokens[10][20], uint8_t *count) {
    uint8_t Lcnt = 0, i = 0, cols = 0;
    while(*str){
        if(*str != delimiter) {
            if(cols < (MAX_COL-1)) {
                tokens[Lcnt][cols] = *str;
                cols++;
            }
        }
        else {
            tokens[Lcnt][cols] = '\0';
            cols = 0;
            Lcnt++;
        }
        str++;
    }
    
    tokens[Lcnt][cols] = '\0';
    *count = Lcnt + 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;
}
