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) {
    // Your logic here
    int val=0;
    while(*str!='\0')
    {
        if (*str==',')
        {      
            *(arr+((*count)++))=val;                  
            // printf("*str=%c val=%d *arr=%d \n",*str,val,*(arr+((*count))));
            val=0;
        }
        else if((*str>='0')&&(*str<='9'))
        {
            val = (val*10)+(uint8_t)(*str-'0');
            // printf("*str=%c val=%d \n",*str,val);
        }
        str++;
    }
    // printf("*count=%d val=%d \n",*count,val);
    *(arr+((*count)++))=val;
}

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++;
    }

    uint8_t arr[20];
    uint8_t count = 0;

    parse_csv_to_array(str, arr, &count);

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