📚 C Syntax – Learn Basic Structure of a C Program

Before diving deep into C programming, it’s important to understand its basic syntax. Every C program follows a simple structure, and knowing it helps you write clean and error-free code!

🔍 Key Elements of C Syntax

Here are the basic building blocks you’ll see in every C program:

  • #include <stdio.h>: Used to include standard input/output library.
  • main() function: The entry point where your program begins.
  • Curly Braces { }: Enclose the body of functions.
  • Semicolon ;: Every C statement ends with a semicolon.
  • Comments: Use // for single-line or /* ... */ for multi-line comments.

📝 Example: Basic C Syntax

This example shows how a simple C program is structured using the correct syntax.

#include <stdio.h> // Include Standard I/O Library

int main() {
    // Print a message
    printf("Syntax is everything!\n");
    return 0;
}

🧠 Why Syntax Matters

In C, **syntax errors** can prevent your program from compiling. Forgetting a semicolon or misplacing a brace is like trying to bake a cake with the wrong ingredients. 🍰

💬 Comments in C

You can use comments to explain your code. They’re ignored by the compiler but great for human understanding!

  • // This is a single-line comment
  • /* This is a multi-line comment */

🎯 Quick Recap

  • Every statement ends with a ;
  • Use { } to define code blocks
  • main() is the starting point
  • Use comments to explain your logic

🧪 Practice Time

Write a program that prints 2 lines using correct syntax and includes at least one comment.
