Learning Objective

At the end of the lesson you will be able to explain the main steps in constructing a computer program and why instructions must be clear and ordered.

What Is a Computer Program?

A computer program is a set of instructions that tells a computer what to do. These instructions are written using programming languages like Scratch, Python, or Java.

Step 1: Identify the Problem

The first step is to decide what you want the program to do. This means understanding the problem you are trying to solve.

Step 2: Plan the Solution (Algorithm)

Next, you create a step-by-step plan called an algorithm. This plan breaks the problem into clear steps for the computer to follow.

Step 3: Write the Program (Coding)

Now, use a programming language to write the instructions based on your plan. Coding turns your ideas into computer commands.

Step 4: Test and Debug

Run your program to check if it works as expected. If there are mistakes, find and fix them. This process is called debugging.

Example: Calculator App

A calculator app uses clear, ordered instructions to add, subtract, multiply, or divide numbers for the user.
