ECS 36b Homework #5 (programming, 5%)
For this homework, we will experiment programs related to memory. This is a two-persons team project.
Your task is to write a C++ program such that it will create an IOT_Thing object, like in ml_IOT_Thing.cpp, and your
program will print the addresses of every component (vtable pointers for each of child/parent/grandparent classes, and the
attributes). You need to go through the same process for the following four cases –
(1) Single inheritance, (2) Single Virtual Inheritance, (3) Multiple Inheritance (both Thing and Another_Thing), and
finally (4) Virtual Inheritance involving both Thing and Another_Thing.
For each case, you should have a separate program. And, your output should be similar to the Clang tool we presented in
the class, but you need to add memory addresses to each LINE of the output below –
g++ -cc1 -std=c++14 -fdump-record-layouts …
