1. Considering the given C language code; a. Show the stack with all activation record instances, including static and dynamic chains, when execution reaches position 4, 3, 2 and 1 in this order. You will be showing 4 separate stacks corresponding to points 4,3,2,1. b. Find static depths for each subprogram (Main, func1, func2 and func3). c. Calculate the (chain_offset, local_offset) for the variables referenced at locations indicated by (*)
