Parse Comma-Separated Integers into an Array

Code

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

void parse_csv_to_array(const char *str, uint8_t *arr, uint8_t *count) {
    int i = 0;
    char delimit = ',';
    uint8_t current_num= 0;
    *count = 0;
    while(*(str+i)!='\0'){
        if(*(str+i) >= '0' && *(str+i)<='9'){
            current_num = current_num* 10 + (uint8_t)(*(str+i)-'0');
        }
        if(*(str+i)==delimit || *(str+i+1)=='\0'){
            arr[*count] = current_num;
            (*count)++;
            current_num = 0;
        }
        
            
        i++;
    }
}

int main() {
    char str[101];
    fgets(str, sizeof(str), stdin);

    // Remove newline
    uint8_t i = 0;
    while (str[i]) {
        if (str[i] == '\n') {
            str[i] = '\0';
            break;
        }
        i++;

    parse_csv_to_array(str, arr, &count);

    for (uint8_t i = 0; i < count; i++) {
        printf("%u", arr[i]);
        if(i < count - 1){
