Transcribed Image Text:1. Write the definition of a function that evaluates three doublenumbers and retums trueif the floor of the
product of the first two numbers equals the floor of the third number; otherwise it returns false.
a. The precondition for this function is that the input to the function consists of three double numbers. The
postcondition is that it returns a Booleanvalue that is true if the floor of the product of the first two numbersis
equal to the floor of the third, otherwise the function returns false.
b.The input into the function is passed by value, the calculations are performed and evaluated inside the
function, and the functionreturnstrue or false (a boolvalue).
c.The caller of this function is expected to supply the input values and output a message to the display
describing the results (i.e., "The floor of the product of the first two numbers is equal to the floor of the third
number" or "The floor of the product of the first two numbers is NOT equal to the floor of the third").
d. In your program, provide the prototype for this function and comments documenting the preconditions
and postconditions (either before or after the prototype).
e. Place the function definition after the main function.
2. Write the definition of a function that calculates the sum and average of the numbers in an interval.
a.The preconditionsarethat the input to the function is two integer values and that the first number is less
than the second number.
i. Make sure to provide code inside the function that ensures the preconditions are met. For example, if the
end points of the interval are passed in the wrong order, your code would need to adjust them.
b.The postcondition is that the sum of the numbers in the interval and the average of the numbers in the
interval is returned. Since a function can only return a single result, your function would be declared as a
voidfunction and the results would be returned through reference parameters that are declared in the caller.
i. Notice that the postcondition does not say anything about displaying these values. The caller of the function
decides what to do with the values after the function calculates them.
c. In your program, provide the prototype for this function and comments documenting the preconditions and
postconditions (either before or after the prototype).
d. Place the function definition after the main function.
