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
    uint8_t no = 0;
    while(*str!='\0'){
        char ch = *str;
        if(ch>='0' && ch<='9'){
            no = no*10 + ch-'0';
        }
        if(ch==','){
            *(arr) = no;
            (*count)++;
            no = 0;
            arr++;
        }
        str++;    
    }
    // last number to be added to the arr
    *(arr) = no;
    (*count)++;
    return;
}

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(" ");
        }
