C Fundamentals

1What is C?✨

C is a powerful, low-level programming language that gives you control over computer hardware. It is widely used for system programming, embedded systems, and performance-critical applications.

2Why Learn C?🎯

• ✓ Foundation for understanding computer science concepts
• ✓ Used in operating systems like Linux and Windows
• ✓ Essential for hardware programming and embedded systems
• ✓ Great stepping stone to other languages like C++ and Rust

3Your First Program💡

Every programmer writes this first:
#include <stdio.h>
int main() {
    printf("Hello, World!\n");
    return 0;
}

This tells C to display text on the screen.

4C Basics🚀

• Syntax is important in C; every line matters
• printf() is used to show output to the screen
• C is a compiled language, which means it needs to be translated to machine code
• Variables must be declared with a specific type

5Data Types in C🔍

• int: for integers
• float: for decimal numbers
• char: for single characters
• double: for large decimal numbers

6Example:⭐

int age = 16;
float height = 5.6;

7What You'll Build This Grade🧩

• ✓ Simple command-line applications
• ✓ Games that use basic logic
• ✓ Programs that manipulate data
• ✓ Tools for solving mathematical problems
