IPO Model

An Input-Processing-Output (IPO) Model is a tool that helps to design basic programs. By using an IPO Model, it eases the process of translating our requirements to code.

Our Example Problem

The client has requested for a Fahrenheit to Celsius converting program

Input Analysis

Input: Analyzing the inputs that the program requires to solve the given problem

• The program needs to be given a Fahrenheit value.

• It should be a numeric value that supports decimals and negatives

Processing Analysis

Processing: Analyzing how we would use the input to calculate or process our inputs and variables

    let F represent fahrenheit
    let C represent celsius
    
    (F − 32) × 5/9 = C

• To convert a Fahrenheit temperature to Celsius, we can use the the formula stated above

Output Analysis

Output: Stating the expected output after processing is done

• The program can output the conversion as a text
