What is C Programming?

• Definition:

  • General-purpose programming language
  • Wide range of applications, originally developed to rewrite the Unix operating system.

• Modern Applications:

  • Used in web browsers (e.g., Google Chrome, Firefox)
  • Database management systems (e.g., MySQL)
  • Hundreds of other applications.

Is C Outdated?

• Common Misconception:

  • While new languages (Python, JavaScript) are popular, C is not outdated.

• Reasons for Continued Popularity:

  • Fast and efficient, ideal for performance-critical applications (compilers, operating systems).
  • Allows deeper hardware access compared to modern languages.

• Job Demand:

  • 18,000 active job openings for C programmers in the U.S. (according to Glassdoor).

• Educational Value:

  • Many universities teach C as a first language, fostering understanding of software-hardware interaction.

Should You Learn C?

• Importance of Learning C:
  • Essential for a deeper understanding of programming.
  • Quote by Joel Spolsky: "If you can't understand why this code copies a string, you are programming based on superstition."

Resources Offered

• C Programming Course:
  • Available on the mobile app with certification at the end.
  • Free course with built-in compiler for practice.
  • Access via QR code or link in the video description.

Setting Up the Environment

Writing Your First C Program - Hello World

1. Program Purpose:
   • Displays "Hello, World!" on screen.
2. Basic Structure of C Program:
   • Main function: int main() { ... }
   • End with return statement (good practice).
   • Import necessary libraries: #include <stdio.h>
   • Print statement: printf("Hello World");
3. Execution:
   • Code run results in output: "Hello World"

Key Takeaways

• Every C program starts with the main function.
• Code is written inside curly braces.
• Practice is essential; watch and write code simultaneously.
