Reconsider the C-like program shown in Exercise 3, this time assuming display registers are used to access frames (rather than static links). Explain how the values of a, b and c are accessed in r's print statement.
Exercise 3
Consider the following C-like program that allows subprograms to nest. Show the sequence of frames, with static links, on the stack when r(16) is executed assuming we start execution (as usual) with a call to main(). Explain how the values of a, b and c are accessed in r's print statement.
