In this homework, you are tasked with designing a program using pseudo code that converts temperature from Fahrenheit to Celsius. The user will input a temperature in Fahrenheit, and the program should output the equivalent temperature in Celsius. The solution must demonstrate good programming practices, including modular programming. You should structure your pseudo code into functions or modules that perform specific tasks, such as reading user input, calculating Celsius, and displaying the result. Emphasize clarity, logical flow, and reusability in your pseudo code design.

Paper For Above instruction

The objective of this assignment is to develop a pseudo code program that converts temperatures from Fahrenheit to Celsius, exemplifying good programming practices including modular design. The task involves creating a user-friendly, logical, and maintainable pseudo code structure that can be easily translated into any programming language. Additionally, some mathematical expressions are evaluated to demonstrate understanding of operator precedence and arithmetic operations.

Introduction

Temperature conversion is a common computational task in various scientific, engineering, and everyday applications. The Fahrenheit to Celsius conversion formula is straightforward, but emphasizing modular programming in pseudo code reinforces essential software engineering principles such as code reuse, clarity, and structured logic. Moreover, understanding expression evaluation is fundamental for debugging and writing correct algorithms. This paper discusses the design of such a pseudo code program, highlighting modular programming techniques and the evaluation of various expressions.

Designing the Program in Pseudo Code

The core of the program involves:

  1. Reading user input in Fahrenheit
  2. Converting Fahrenheit to Celsius using the formula: Celsius = (Fahrenheit - 32) * 5/9
  3. Displaying the result to the user

To ensure modularity, the pseudo code will be divided into distinct functions:

  • ReadFahrenheit(): Handles user input
  • ConvertToCelsius(fahrenheit): Performs the temperature conversion
  • DisplayResult(celsius): Outputs the converted temperature

Pseudo Code Implementation

FUNCTION ReadFahrenheit()


DISPLAY "Enter temperature in Fahrenheit:"


INPUT fahrenheit


RETURN fahrenheit


END FUNCTION


FUNCTION ConvertToCelsius(fahrenheit)


celsius := (fahrenheit - 32) * 5 / 9


RETURN celsius


END FUNCTION


FUNCTION DisplayResult(celsius)


DISPLAY "Temperature in Celsius: ", celsius


END FUNCTION


// Main program


BEGIN


fahrenheit := ReadFahrenheit()


celsius := ConvertToCelsius(fahrenheit)


DisplayResult(celsius)


END

This modular pseudo code ensures a clear separation of concerns, facilitates testing, and simplifies future modifications. For example, changing the conversion formula or input method can be done within their respective functions without affecting the overall flow.

Evaluation of Numeric Expressions

The set of expressions provided demonstrates operator precedence, associativity, and the difference between integer and floating-point division.

  • 3 + 6: Addition, result = 9
  • 3.4 – 2.1: Subtraction, result ≈ 1.3
  • 2 * 3: Multiplication, result = 6
  • 8 / 2: Division (assuming integer division in some languages), result = 4; in floating point, 8.0/2.0 = 4.0
  • 8 / 8: Result = 1; also 8/8 = 1
  • 8 / 9: Result ≈ 0.888... (floating point division)
  • 8 / 7: ≈ 1.14
  • 8 % 8: Modulo, result = 0
  • 8 % 9: Since 8
  • 8 % 7: Result = 1, as 8 divided by 7 leaves a remainder of 1
  • 0 % 2 3: Zero modulo 2 is 0; 0 3 = 0
  • 10 % 3: Result = 1, as 10 divided by 3 leaves a remainder of 1
  • - 4 / 2: Negative division, result = -2
  • 5.0 2.0 / 4.0 2.0: Following operator precedence, multiplication and division are evaluated left to right:

    - 5.0 * 2.0 = 10.0

    - 10.0 / 4.0 = 2.5

    - 2.5 * 2.0 = 5.0

  • 10 / 3 + 5: 10 / 3 ≈ 3.33 (floating point), plus 5 yields approximately 8.33

The last expression % + (4 / (6 / % 5 / 3 appears incomplete and syntactically invalid. A correction or clarification is necessary to evaluate or interpret it meaningfully.

Conclusion

This exercise underscores the importance of structured, modular pseudo code in software development, especially for tasks such as temperature conversion. The modular design promotes code clarity, maintainability, and ease of debugging. Furthermore, understanding operator precedence and expression evaluation is foundational for writing correct algorithms. Properly managing incomplete or ambiguous expressions is also crucial to avoid logical errors. Overall, these skills contribute to developing efficient, reliable programs applicable in various technical and scientific contexts.
