# Answer to Question #32370 in C++ for amal

Question #32370

Print the source code of this program plus the output of the following four executions:

• Execution 1: Input the weight as a negative number of ounces.

• Execution 2: Input the weight as 0ounces.

• Execution 3: Input the weight as 5 ounces.

• Execution 4: Input the weight as 42 ounces.

Write three independent functions for this program assignment as follows:

• One function to read the required input values.

• A second function to perform the required calculations using the input values from the first function.

• A third function to display the results of the second function.

Speedy-Pants Delivery Inc. charges by weight for delivery of packages. The delivery charge for the first pound is $3.00 and $0.50 is added onto the charge for each additional four ounces.

For example:

A package weighing more than 16 but at most 20 ounces costs $3.50 to deliver.

A package weighing more than 20 but at most 24 ounces costs $4.00 to deliver. etc.

Write a program that inputs the weight of a package in ounces, computes the charge for delivery, and displays it to the screen. NOTE: One pound equals 16 ounces.

Note:

(1) Use a double-valued function, weight_input, to prompt the user for input.

(2) Use a double-valued function, compute_delivery_charge, to compute the charge for delivery.

(3) Use a void function, display_delivery_charge, to display the delivery charge.

{

double i;

cout << "Input the weight in ounces: ";

cin >> i;

while (i <= 0)

}

return i;

}

double computeDeliveryCharge(double weight)

{

double c = 3.0;

if (weight <= 16) return c;
