Question

A retail store grants its customers a maximum amount of credit. Each customer's available credit is his or her maximum amount of credit minus the amount of credit used. Write a pseudocode algorithm for a program that asks for a customer's maximum credit and amount of credit used, then calculates and displays the customer's available credit.

Short answer

Answer: To calculate the available credit for a customer, subtract the credit used from the maximum credit (available_credit = max_credit - credit_used).

Step-by-step solution

Ask for the customer's maximum credit

First, we need to ask the customer for their maximum amount of credit. The input should be stored in a variable, let's call it max_credit.

Ask for the customer's amount of credit used

Next, we need to ask the customer for the amount of credit they have used so far. This input should be stored in another variable, let's call it credit_used.

Calculate the available credit

Now that we have the maximum credit and the credit used, we can calculate the available credit. To do this, subtract the credit used from the maximum credit: available_credit = max_credit - credit_used.

Display the available credit

Finally, we need to display the customer's available credit. To do this, simply output the available_credit variable. The pseudocode algorithm should look like this: 1. Ask for max_credit 2. Ask for credit_used 3. available_credit = max_credit - credit_used 4. Display available_credit
