• Comprehensive, well-organized, practical course
• No prior programming knowledge required
• Instructor: Mosh Hamedani (20+ years experience)

Importance of C++

• Popular programming language, widely used in:
  • Performance critical applications
  • Video games
  • Device drivers
  • Web browsers, servers, operating systems
• Used by major companies like Adobe, Google, Microsoft, Netflix, and NASA
• New versions released approximately every 3 years (Latest: C++20)
• C++ is still one of the fastest and most efficient programming languages

Career Opportunities

• C++ as a foundational programming language for Computer Science students
• Average C++ programmer salary in the U.S. is over $170,000/year

Learning Objectives

1. Learn the C++ language syntax
2. Understand C++ Standard Library
   • Collection of pre-written code
   • Includes data structures and algorithms

Course Structure

• Step-by-step learning approach with cool program development
• Plenty of exercises to strengthen problem-solving skills

Tools for C++ Development

Integrated Development Environments (IDEs)

• IDEs make coding easier through built-in editors, debugging tools.
• Popular IDEs:
  • CLion: Cross-platform with a free trial (recommended)
  • Microsoft Visual Studio: Community Edition is free (Windows)
  • Xcode: For Mac

Getting Started with CLion

1. Download and install CLion.
2. Create a new C++ project:
   • Specify project location
   • Set C++ standard version (recommended: C++20)
3. Write your first program (Hello World).

Basic Program Structure

• Every C++ program has a main function, which is the entry point
• Main function examples:

  int main() {
      std::cout << "Hello World";
      return 0;
  }
  

• std::cout: Used for output, part of C++ standard library

Important Concepts

Variables

• Declaration: Specify data type and variable name
  • Example: int fileSize = 100;
• Initialization: Assigns a value to the variable at the same time it is declared

Constants

• Used to store values that shouldn’t change
  • Use const keyword
  • Example: const double pi = 3.14;

Naming Conventions

• Use meaningful names for variables
• Popular conventions: Snake Case, Pascal Case, Camel Case, Hungarian Notation

Mathematical Expressions

• Basic operations: Addition, Subtraction, Multiplication, Division
• Order of operations important (use parentheses for clarity)
  • Example: int x = (1 + 2) * 3;

Input/Output

• std::cin: Used to read from the console
  • Example:

  int value;  
  std::cin >> value;
  

• Techniques for displaying output clearly on the console

Using the Standard Library

• Includes functionalities for mathematical operations, file handling, etc.
• Useful for avoiding repeated code and improving efficiency

Summary

• This section covers the foundational concepts of C++ relevant for further development.
• Regular exercises encouraged to build skills and confidence.

Next Steps

• Explore fundamental data types in detail
• Learn about working with strings, arrays, and more advanced topics.
