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 num = 0;
    *count = 0;
   while(*str != '\0') {
    char ch = *str;
    if(ch >='0' && ch<='9'){
        num = num * 10 + (ch - '0');
    } else if(ch ==',') {
        arr[*(count)] = (uint8_t)num;
        (*count)++;
        num = 0;
    }  
    str++;
   }
    arr[*count] = (uint8_t)num;
    (*count)++;
}

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(" ");
        }
    }
    return 0;
