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.
