1. (10 pts) Show the run-time stack with all activation record instances, including static and dynamic chains, when execution reaches position 1 in the following skeletal program (in C-style syntax). Assume that the programming language is statically scoped but does not allow functions as return values. void Foo ) void B (int) void A void c O /I position 1 c Oi void B (int flag) void D O B (1)i if (flag) A Oi else D Oi B (0)i The calling sequence for this program for execution to reach C is: main calls Foo, Foo calls B, E calls D, D calls B, B calls A, and A calls C 1.
