1) (2 points) Your task is to indicate what must go in place of the XXX in order to print the described output with the following code: num=13; fprintf("Number:XXX', num); Output: Number:13 Note that indicates that there will be an actual space - so, it would look like this: Number: 13 Where there are two spaces between the colon ':' and the 'T'. 2) (5 points) You wish to write a function that will take two inputs (number and choice) that will return one answer (called answer). It will return number* number if choice is 1, pi*number* number if choice is 2 and 0 if choice is anything else. Using any method you'd like, write a function that will accomplish this task. I've started it for you below. function end 3) (3 points) The code below is intended to display "Circle" if the user enters a 1, "Square" if the user enters a 2, and "Triangle" if the user enters anything else. Indicate the THREE errors in the code below and provide corrections. selection = input('Please select a number'); if (selection = 1) disp('Circle'); else if (selection == 2) disp('Square'); otherwise disp('Triangle'); end
