Control Structures and Loops
Master conditional statements (if/else) and various loop constructs (for, while) for dynamic contract behavior.
Control Structures Intro
Welcome to Lesson 2! Today, we'll learn about control structures in Solidity. These are essential for making your smart contracts dynamic and responsive.
Control structures allow your contract to:
- Make decisions based on conditions.
- Repeat actions multiple times.
- Execute different code paths.
Think of them as the 'brain' of your contract, guiding its behavior.
Conditional 'if' Statements
The simplest control structure is the if statement. It executes a block of code only if a specified condition is true.
The condition must evaluate to a bool (true or false). If true, the code inside the curly braces {} runs; otherwise, it's skipped.
