Control structures are fundamental building blocks in programming that dictate the flow of execution in a program. They allow developers to make decisions, repeat actions, and organize code logically. Let's explore the core concepts:
1. Conditional Statements 🟢
Conditional statements execute code based on whether a condition is true or false. Common examples include:
if
statementselse if
laddersswitch
cases
💡 Tip: Use
if
/else
for simple decisions andswitch
for multiple options.
2. Loops 🔁
Loops repeat a block of code until a specific condition is met. Types include:
for
loops (fixed iterations)while
loops (conditional repetitions)do-while
loops (execute once before checking)
📌 Pro Tip: Always include a termination condition to avoid infinite loops!
3. Functions 🧩
Functions encapsulate reusable code blocks. Key features:
- Input parameters
- Return values
- Scope of variables
🚀 Bonus: Learn how to create custom functions in our Programming Languages Guide.
4. Branching & Jumping 🧭
break
andcontinue
for loop controlgoto
(less common, but still used in some languages)throw
/catch
for error handling
