Input/Output CS Thinking Example 2

Follow the full solution, then compare it with the other examples linked below.

Example 2

medium
A temperature converter takes a Celsius value as input and outputs the Fahrenheit equivalent. Write pseudocode and identify the input, process, and output.

Solution

  1. 1
    Step 1: Input: celsius = INPUT('Enter temperature in Celsius').
  2. 2
    Step 2: Process: fahrenheit = celsius * 9/5 + 32.
  3. 3
    Step 3: Output: OUTPUT fahrenheit. This follows the Input-Process-Output (IPO) model that describes how most programs work.

Answer

Input: Celsius value. Process: multiply by 9/5 and add 32. Output: Fahrenheit value.
The Input-Process-Output model is a fundamental way to understand program structure. Identifying these three stages helps in planning and designing programs.

About Input/Output

The mechanisms by which a program receives data from the outside world (input) and sends results back (output). Input can come from keyboards, files, sensors, or network connections; output can go to screens, files, printers, or other devices.
