Consider the following class hierarchy. class A { } int a = 0; int f (int x) {...} int g (int x) {...} class B extends A { int b = 7; int f (int x) { ... } } Explain how a compiler stores objects of classes A and B in memory. What are the key challenges in the compilation of such class hierarchies (about accessing member variables and invoking methods)? How does the layout that you describe solve these problems? You may want to use appropriate diagrams to illustrate your answer.
