Create Your Own Function In C That Accepts One Input And Ret

Create Your Own Function in C That Accepts One Input and Returns a Float

Create a C program that defines a custom function which takes one input parameter and returns a float number. You may choose any theme or calculation for the function. The program should include the function's implementation, an example call, and an explanation of what the function does. Test your function with several test cases, display the results, and include a test case table. Submit your work as a Word or PDF file, including screen captures of your code execution in an online compiler.

Paper For Above instruction

The goal of this assignment is to create a user-defined function in C that accepts a single input parameter and returns a float value, illustrating understanding of function creation, input/output handling, and testing in C programming. For this particular task, I have designed a function called CalculatePercentage, which geometrically interprets an input number as a part or portion of a whole, returning its percentage as a float. This function takes an integer input representing a part of a whole, with the assumption that the total or maximum value to compare against is 100 (or another fixed base if adjusted). The idea behind this is to demonstrate how functions can process inputs, perform calculations, and return floating-point results that can be more precise and suitable for fractional or decimal data.

The structure begins with the main function, which prompts the user to enter an integer value. It then calls the CalculatePercentage function, passing the input value as its argument. The function computes the percentage by dividing the input value by a fixed total (for example, 100) and returns this as a float, representing the percentage of the total. This simulates real-world scenarios where percentages are computed from known parts.

Here is the overview of how the function operates: If the user inputs a value less than or equal to the total (say 100), the function divides the input by the total, returning a floating-point number between 0 and 1, which can be interpreted as 0% to 100%. If the input exceeds 100, the function still performs the division and may return a value greater than 1, indicative of exceeding 100%. This flexibility permits diverse inputs and responses, reflecting realistic situations in data analysis or progress tracking.

The program includes multiple test cases, such as inputting 50 (expected 50%), 75 (expected 75%), and 120 (expected 120%), to demonstrate how the function handles typical and edge values. The outputs are formatted as percentages for clarity. Additionally, screen captures of the program running in an online compiler, such as ideone or repl.it, are included to validate the correct implementation and output formatting.

Overall, this task emphasizes function creation, return types (specifically float), input handling, output formatting, and testing—core skills essential to proficient C programming. The code adheres to best practices by including comments, clear variable names, and structured flow to facilitate understanding and debugging.
