1. Stacks (10 points) Draw a sequence of diagrams, one for each problem segment, that represent the current state of the stack after each labeled set of operations. If an operation or instruction produces output then indicate what that output is. hStack is the handle of a stack opaque object that can hold characters. There is no diagram for init or destroy. hStack = stack_init_default(); i. stack_push(hStack, 'a'); i. stack_push(hStack, 'b'); iii. printf("\%c'", stack_top(hStack)); stack_pop(hStack); iv. printf("\%c" , stack_top(hStack)); stack_push(hStack, 'c', ); v. stack_push(hStack, 'd'); stack_push(hStack, 'e'); vi. printf("\%c ", stack_top(hStack)); stack_push(hStack, 'f') ; vii. stack_pop(hStack); stack_push(hStack, ' 'g'); stack_destroy (khStack)
