Programming logic
Learn the logic behind the code
Syntax changes from language to language, but the underlying logic stays the same. This guide focuses on the ideas you need to understand first, so the code you write later makes more sense.
Three core ideas
Concepts that carry across languages
Most programming languages share the same building blocks. Mastering these three ideas gives you a foundation you can reuse everywhere.
Step 1
Memory and variables
A variable is a named place that holds a value while your program runs. Learning how values are stored and changed helps you predict what your program will do next.
Step 2
Branching logic
Conditionals let a program choose between paths based on a question. Drawing a simple decision tree on paper makes each possible outcome easy to follow.
Step 3
Function modularity
A function groups steps under one name so you can reuse them. Breaking a large task into smaller functions makes each part easier to test and understand.
The core idea
Code is structured problem solving. If you can trace the steps, you can learn to program in any language.— lernercity
