The assignment involves creating a program that converts temperature values from Fahrenheit to Celsius, ensuring the input temperature is non-negative, and allowing the user to repeat the process as desired.

Paper For Above instruction

Temperature conversion is a common computational task that involves converting a given temperature from one measurement system to another, specifically from Fahrenheit to Celsius in this context. The core objective of this program is to facilitate such conversions interactively, offering users the ability to input temperatures, verify the input constraints, perform the conversion, and decide whether to repeat the process.

The program begins with essential header inclusions, namely <iostream> for input-output operations and <iomanip> for formatting the output. Utilizing the standard namespace allows for concise code. The main function initializes variables: a double for Fahrenheit temperature (`ftemp`), a double for Celsius temperature (`ctemp`), and a character (`choice`) to control the repetition loop. The `do-while` loop encapsulates the core logic, enabling repeated conversion based on user input.

Within each iteration, the program prompts the user to enter a temperature in Fahrenheit. It validates the input by ensuring the temperature is not negative. If a negative value is entered, the user receives an error message and is prompted to re-enter the temperature until a valid, non-negative value is provided. The conversion formula used is:

  • Celsius = (Fahrenheit - 32) * 5/9

To enhance readability, the output format is set to fixed-point notation with two decimal places, and positive signs are explicitly shown for positive Celsius temperatures. After displaying the converted temperature, the program asks whether the user wishes to continue, accepting 'Y' or 'N' as input, with the process repeating unless the user chooses to exit by entering 'N'.

This implementation emphasizes input validation, user interaction, and formatted output, which are fundamental elements in developing user-friendly console applications. Proper validation ensures accurate computations, while formatted output improves clarity. The program's loop-control structure facilitates repeated execution without restarting, making it efficient and user-centric.
