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
    *count=0;
    int start=0;
    
    uint8_t val=0;
    for (int i=0; str[i]!='\0';i++){
        if (str[i]==',') {
            for (int j=start;j<i;j++){
                 val=val*10+str[j]-'0';
            }
            
            arr[(*count)++]=val;
            start=i+1;
            val=0;
        }

        
        
       
       
    }

    for (int j=start;str[j]!='\0';j++){
        val=10*val+str[j]-48;
    }
    
    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(" ");
