Lecture Notes: Introduction to C Programming

Instructor Introduction

• Instructor: Faduma Manandar, Software Developer at Programiz
• Series Focus: Comprehensive guide to C programming

Overview of C Programming

• What is C?

  • General-purpose programming language
  • Initially developed to rewrite Unix OS
  • Used in applications like Google Chrome, Firefox, MySQL

• History of C

  • Created in the 1970s
  • Still relevant despite newer languages like Python and JavaScript

Importance of C

• Is C Outdated?

  • No, C remains popular
  • Known for its speed and efficiency
  • Ideal for applications requiring high efficiency (e.g., compilers, operating systems)
  • Allows deeper hardware access than many modern languages

• Demand for C Programmers

  • 18,000 active job openings in the US (source: Glassdoor)
  • Often taught as a first language in universities
  • Facilitates understanding of software-hardware interaction

Benefits of Learning C

• Provides fundamental understanding of programming
• Helps with understanding memory management and hardware interaction
• Quotation: "If you can't understand why this code copies a string, you are programming based on superstition." - Joel Spolsky

Resources for Learning C

• Programiz offers a free C programming mobile app
  • Includes a structured course and certification
  • Built-in compiler for practice
  • Accessible via QR code or video link

Setting Up to Code in C

• Requirement: C compiler and text editor
• Online Tool: Programiz's online C editor
  • URL: www.programmys.com/c-programming/online-compiler
  • Enables running C code in the browser

Writing a Simple C Program - "Hello World"

• Program Structure:

  • 'int main()' function with curly braces
  • Marks the starting point of the program
  • Use of 'return' statement for good practice

• Importing Libraries:

  • Use #include <stdio.h> to import necessary functions

• Printing Text:

  • Use printf("Hello World"); to display text

• Key Points:

  • Code is written inside curly braces of the main function
  • Simplified introduction to C programming

Learning Approach and Next Steps
