Square Area Calculator

Contributors: Chris Chen, Xinxian Huang

This program uses the side length of a square inputted by the user to calculate the area of the square.

Explanation of Code

Line 4: A "while" loop is used to continuously iterate until a valid square length input is provided. "while True:" indicates that the loop will run indefinitely until a "break" statement is encountered within the program, terminating the loop.

Line 6: Prompt the user to enter the side length of the square using the "print()" function.

Line 9: Declare the variable "square_length" and assign it the value inputted by the user. The "int()" function is utilized to convert the string value from "input()" into an integer, enabling arithmetic operations.

Line 12: Employing an "if statement," verify if the user inputted a positive value. This condition is assessed using the comparison statement: "square_length > 0". If true, proceed to execute the code within the "if block."

Line 14: Define the variable "square_area," which will store the resulting area. "square_length ** 2" calculates the area of the square by squaring the side length provided by the user.

Line 17: Utilizing the "print()" function and the variable "square_area," output a message concatenated with the calculated area of the square.

Line 20: The "break" statement is used to exit the while loop defined in Line 4.

Line 21: An "else" statement accompanies the "if statement" from Line 12 to handle tasks if the condition evaluates to false.

Line 23: Output an error message using the "print()" function, prompting the user to input a valid parameter for the variable "square_length." Since there is no "break" statement here, the code will return to Line 6 to prompt for input again.
