3. Why C? The Foundation of Modern Software C is the bedrock of countless systems we use daily. It offers unparalleled control over hardware and memory.

4. Getting Started: Your First C Program Let's write the classic "Hello, World!" program. This simple code will print a message to your screen, introducing you to the basic structure of a C program. #include <stdio.h>int main() { printf("Hello, World!\n"); return 0;} • #include <stdio.h>: Includes the standard input/output library. • int main(): The main function where program execution begins. • printf(): A function to print output to the console. • return 0: Indicates successful program execution.

5. Core Concepts: Variables and Data Types Variables are containers for storing data. In C, you must specify the type of data a variable will hold before you use it. 1 2 Integers (int) Floating-Point (float/double) For whole numbers: int age = 30; For decimal numbers: float price = 19.99; 3 4 Characters (char) Arrays For single letters: char initial = 'J'; Collections of same-type data: int scores[] = {85, 90, 78};

6. Control Flow: Making Your Program Smart Conditional Statements (if/else) Loops (for, while) Execute different blocks of code based on whether a condition is true or false. Repeat a block of code multiple times. if (score >= 60) { printf("Pass!\n");} else { printf("Fail!\n");} for (int i = 0; i < 5; i++) { printf("%d ", i); // Prints 0 1 2 3 4}

7. Functions: Organize, Reuse, Conquer Functions break down large programs into smaller, manageable units, making your code cleaner, more readable, and easier to debug. 1 2 Modularity Reusability Divide and conquer complex problems. Write once, use many times. 3 4 Readability Debugging Easier to understand code logic. Isolate and fix issues faster.

8. Your Next Steps in C Where C Shines Continue Your Journey • Operating Systems: Linux, Windows kernels are largely written in C. Practice consistently, build small projects, and explore online tutorials. The C community is vast and supportive! • Embedded Systems: Microcontrollers, IoT devices. • Game Development: High-performance engines. • Compilers & Interpreters: Tools for other languages.
