Making programs think

So far, your programs run top to bottom, executing every line. But real programs need to make decisions - “if this, then that”. Control flow is what makes programs intelligent!

What you’ll learn

If statements

Make decisions based on conditions

Real-world examples

Decision-making is everywhere:
  • ATM: IF password correct, THEN allow access
  • Apps: IF user clicks button, THEN perform action
  • Weather app: IF temperature < 0, THEN show snow icon
  • Games: IF health = 0, THEN game over

Prerequisites

Before starting this section, make sure you understand:
  • Variables and data types
  • Operators (especially comparison operators)
  • Boolean values (True/False)
Control flow is where programming gets fun! You’ll start building programs that can actually make decisions and respond to different situations.

Let’s begin!

Start with the foundation of all program logic: if statements.
