Q & A

What programming language is being used to create the simple calculator?

The simple calculator is being created using the 'Receipts' programming language.

What basic arithmetic operations will the calculator support?

The calculator will support addition, subtraction, multiplication, and division operations.

How does the calculator handle division by zero?

The calculator checks if the second number is zero before performing the division operation to avoid a division-by-zero error.

What is the role of the 'namespace' in this program?

The 'namespace' is used to define and organize functions and variables within the program, allowing for better structure and clarity in the code.

What data type is used to store the numbers entered by the user?

The numbers entered by the user are stored in variables with a data type that is compatible with numerical values, likely integers or floats.

How are the results displayed after performing an operation?

Once an operation is performed, the result is displayed to the user, allowing them to see the outcome of the calculation.

How does the program handle user input for operations?

The program prompts the user to enter two numbers and then select an operation (addition, subtraction, multiplication, or division), performing the chosen operation on the entered numbers.

What happens if the user enters an invalid operator?

If an invalid operator is entered, the program displays a message indicating that the operation is not valid.

Can the program handle multiple operations in sequence?

Yes, the program can handle multiple operations in sequence, allowing the user to continue performing calculations without restarting the program.

What improvements can be made to the calculator program?

Improvements could include adding more advanced mathematical functions (like square roots, exponents), user input validation, and a more user-friendly interface.
