Question

Available Credit Design a hierarchy chart for a program that calculates a customer’s available credit. The program should carry out the following steps: 1\. Display the message “Enter the customer’s maximum credit.” 2\. Wait for the user to enter the customer’s maximum credit. 3\. Display the message “Enter the amount of credit used by the customer.” 4\. Wait for the user to enter the customer’s credit used. 5\. Subtract the used credit from the maximum credit to get the customer’s available credit. 6\. Display a message that shows the customer’s available credit.

Short answer

Question: Design a hierarchy chart for a program that calculates a customer's available credit, following the given step by step solution.

Step-by-step solution

Display the message "Enter the customer's maximum credit."

Show a message to the user, asking them to enter the maximum credit for the customer.

Wait for user input for the customer's maximum credit

Get the user's input for the maximum credit and store it in a variable, for example, max_credit.

Display the message "Enter the amount of credit used by the customer."

Show another message to the user, asking them to enter the credit used by the customer.

Wait for user input for the customer's credit used

Get the user's input for the used credit and store it in a different variable, for example, used_credit.

Calculate customer's available credit

Subtract the used_credit from max_credit and store the result in a new variable called available_credit. This can be written as: available_credit = max_credit - used_credit.

Display the customer's available credit

Show the calculated available_credit to the user, displaying a message that indicates the customer's available credit.

Key concepts

Customer Credit Calculation

Calculating the available credit for a customer involves straightforward arithmetic, but understanding the process is key. The available credit is determined by subtracting the amount of credit used by the customer from their maximum credit limit. This calculation allows businesses to determine how much credit a customer has left to use.

Imagine a scenario where a customer has been given a credit limit of $1,000. If they use $400 of this credit, the calculation would be:

• Maximum Credit: $1,000
• Used Credit: $400
• Available Credit: $1,000 - $400 = $600

The available credit is $600, meaning the customer can still use up to this amount without exceeding their limit. This fundamental calculation is important in finance and helps maintain the balance between credit offered and credit utilized.

Input and Output Operations

Input and output operations are crucial in any program that requires user interaction. For the customer credit calculation program, input op...nts to the user.

For instance, the program displays prompts, asking users to enter specific information such as maximum and used credits. These prompts guide users in providing the necessary input. Once the inputs are collected, using other operations, the program processes this data. Finally, using output operations, the program displays the calculated available credit back to the user.

These operations ensure that information can flow between users and systems correctly. Without proper input and output functions, a program cannot effectively interact with its users, making it essential to understand and implement these operations correctly.

Variable Manipulation

Variable manipulation allows the storing and processing of data within a program. In the context of calculating available credit, variables are used to hold different pieces of data and perform operations on them.

In our task, variables like `max_credit` and `used_credit` are initialized to store user inputs. These inputs are manipulated through subtraction to obtain a new variable, `available_credit`, which stores the resulting value. This process involves simple arithmetic to calculate the difference between the total credit and the used credit.

Variable manipulation is fundamental in programming as it allows programs to perform calculations, store dynamic data, and manage state effectively. Understanding how to manipulate variables empowers developers to write flexible and dynamic code that can adapt to various inputs.
