C++ inheritance size with empty derived class object

#include<iostream>using namespace std;class base { int arr[10];};class b1: public base { };class b2: public base { };class derived: public b1, public b2 {};int main(void){ cout << sizeof(derived); return 0;}Since in c++ by default the members of class are private why does the sizeof derived class is 80. The access-specifier private is only related to the accessibility of the members of the base class in the derived class. The derived class contains the sub-objects of the classes it derives from. In this case, it contains b1 and b2 sub-objects. So its ...

this is the main filethis is the settings filepipelines.py fileitems.py fileWhenever I run the scraper, it is supposed to create a json file.

Automatically quits

I'm trying to write a snake game in python but my game automatically quites after inputing out of boundaries code.I don't understand how the coordinates of my rect are >= than the width of my game, because in the screen they are not.
