Flow Control $1$C

Description

The purpose of this challenge is to use the IF statement to control program flow. This challenge simulates using a credit or debit card at the gas pump.

Requirements

Declare a double variable called total

Declare a double variable called gallons

Declare a char variable called payment$\_$type

Declare a double variable called cost. Initialize this value to $2\mathrm{.}55$

Declare a bool variable called authorized. Initialize this value to false.

Ask the user the type of payment that will be made. Use the payment$\_$type variable to receive this user input.

If the user enters a $\text{'}c\text{'},$ it will be a credit card payment

Ask the user to enter a zipcode $($you will have to create a variable to store the value of the zipcode that the user enters; you decide what data type is appropriate$)$

Write a nested$-$if statement and check that the value of the zipcode entered is $93301.$ If the zipcode entered is correct, set authorized to true.

If the user enters a $\text{'}d\text{'},$ it will be a debit card payment.

Ask the user to enter a PIN $($You will have to create a variable to store the value of the PIN that the user enters; you decide what data type is appropriate$)$

Write a nested$-$if statement and check that the value of the PIN entered is $1234.$ If the PIN entered is correct, set authorized to true and change the value of cost to $2\mathrm{.}35.$

If authorized is true, only then will you do the following:

Ask the user how many gallons are being purchased. User will enter a numeric amount. Use gallons variable to hold this amount.

Calculate the appropriate total of the purchase depending on the payment type. Use the total variable to calculate the total amount. Additionally, you will need to add $0\mathrm{.}35$ to the total cost for debit card purchases.

Display the cost of the purchase to the user.

Add an else block after checking if authorized is true. In this section, show an appropriate message indicating an invalid PIN or ZIP code $($see the Sample Interaction below$)$
