You are to do this exam without assistance from classmates or others. You should take no more than 70 minutes to complete this exam of 30 questions. 2 points will be deducted for each full minute over 70 you take to submit the exam. For this exam, no grace period other than this is allowed. Please leave enough time in case Canvas takes a long time (like a minute) to register your exam after submitting your answers.

Ask the user to input the multiplier into the program each time it is run (using a prompt with printf and scanf)

Use this number directly in the expressions that need it.

Use a variable (such as float loadedmultiplier; and assign it the value of, say, 1.2, down in the code of the program.)

Use a defined constant (such as const float loadedmultiplier = 1.2;)

You own an office building, and are writing a program that calculates rents based on square footage. Your inputs will be the number of rooms an office suite has along with the actual square footage. You use something called a "loaded footage multipler" so that you can properly allocate the costs of your hallway and lobby space to each suite. This might be a number such as 1.07 or 1.2. Actual footage is always multiplied by this number to arrive at the chargeable square footage. You like this number, have been using it for the past 10 years, and plan to use it in your building for at least 3 years. You are the programmer and can recompile the source code at any time. Stylewise, how should you best incorporate this value into your program?

1 ptsQuestion 3

age = 23 * yukko (18);

printf("%d", yukko(34.56));

age = yukko (34.56);

yukko (34.56);

If yukko is a function that takes in a float expression and returns an integer (int) value, which of these calls is illegal/inappropriate? Assume age is integer.
