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;
    int j = 0;
    while(str[i] != '\0')
    {
       
        uint8_t num = 0;
        while(str[i] >= '0' && str[i] <= '9')
        {
            num  =  num*10 + (str[i] - '0');
            i++;
        }


        arr[j] = num;
        j++;
        if(str[i] == '\0')
        {
            break;
        }
        i++;
        

    }


    *count = j;


}

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(" ");
        }
