+Project Title: Simple Calculator
+
+Filename: recipe-578599_v2.py
+
+Description: This Python script provides a command-line interface for performing basic arithmetic operations.
+
+Features:
+Supports addition (+), subtraction (-), multiplication (*), division (/), remainder (%), and power (**) operations.
+
+Allows continuous calculations using the previous result as the first number.
+Includes input validation for operators.
+
+Usage:
+Run the script from the terminal: python3 recipe-578599_v2.py
+Follow the prompts to enter numbers and operators.
+Enter 'c' to continue with the previous result or 'q' to exit the application.
+
+Requirements: Python 3 interpreter.
