Write a command-line calculator from scratch in modern C++ that evaluates arithmetic the user types in. You parse an operator and two operands, dispatch on the operation, and guard against division by zero, all with the standard library only. A focused introduction to parsing input and branching cleanly.

What You'll Build
A command-line calculator that reads an expression such as 12 * 7, performs addition, subtraction, multiplication, and division on floating-point numbers, and loops for another calculation.
Learning Objectives

- Work with double and integer arithmetic and understand their differences
- Guard against invalid operations such as division by zero
- Format numeric output with std::cout and <iomanip> manipulators
- Split responsibilities into functions for reading, computing, and printing
