A turnstyle is a gate/barrier with a rotating bar that allows one person at a time to pass through after depositing a token. It has two states, open and locked.
When open, pushing against the bar will rotate it and allow one person to pass through, returning the bar to the locked state.
When locked, depositing a token will unlock the bar, i. e. put it in the open state.
Pushing when locked does nothing (the bar will not move); and depositng a token when open does nothing.

a. Draw the Finite State Diagram of this system (i. e. represent and label the states; show the output(s) associated with each state; and show the transitions associated with the possible values of the input(s)
b. Construct the truth table showing what transitions occur from each state for all possible values of all inputs.

4.11 painting a wall (1) prompt the user to input integers for a wall's height and width. calculate and output the wall's area (integer). note that in this case there is a new line after each prompt. (submit for 1 point). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet (2) extend to also calculate and output the amount of paint in gallons needed to paint the wall (floating point). assume a gallon of paint covers 350 square feet. store this value in a variable. output the amount of paint needed using the %f conversion specifier. (submit for 2 points, so 3 points total). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet paint needed: 0.471429 gallons (3) extend to also calculate and output the number of 1 gallon cans needed to paint the wall. hint: use a math function to round up to the nearest gallon. (submit for 2 points, so 5 points total). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet paint needed: 0.471429 gallons
