• Comprehensive course covering C++ from basics to advanced concepts.
• No prior programming knowledge required.
• Instructor: Mosh Hamedani, software engineer with 20 years of experience.
• Teaches through Code With Mosh platform.

What is C++?

• C++ is a popular programming language for performance-critical applications.
• Common uses: video games, device drivers, web browsers, servers, operating systems.
• Used by companies like Adobe, Google, Microsoft, and NASA.
• New versions every three years, latest being C++20.
• Relevant despite newer languages like Java or C#.
• High demand for C++ programmers (average salary: $170,000 in the US).

Mastering C++

• Two main areas to learn:
  • C++ language syntax and grammar.
  • C++ Standard Library (STL) for pre-written functionalities like data structures and algorithms.
• Course will cover major functionalities of the STL.
• C++ may seem extensive, but learning key concepts is sufficient to write substantial programs.

Tools for C++ Programming

• Integrated Development Environment (IDE) needed:
  • Top Choices:
    • Microsoft Visual Studio (Community Edition - free)
    • Xcode (for macOS)
    • CLion (cross-platform, 30-day trial, then paid)
• Recommended IDE: CLion (can use others).
• Installation guide provided for CLion.

Writing Your First C++ Program

• Explain structure of a C++ program:
  • Starts with main() function (entry point).
  • Case sensitivity is important.
  • Function must return an integer (0 for success).
• Intro to printing output using Standard Library:
  • #include <iostream> for input/output functionalities.
  • Use std::cout for printing.

Concepts Covered

• Variables:

  • Temporary data storage in memory.
  • Declaration syntax: type name = value;
  • Importance of meaningful names and initialization.

• Constants:

  • Use const to prevent value changes.

• Naming Conventions:

  • Snake_case, PascalCase, CamelCase, Hungarian Notation.

• Mathematical Expressions:

  • Operators: +, -, *, /, %.
  • Importance of operator precedence.

• Reading/Writing Console Input:

  • std::cin for input.
  • Validation of user input and handling floating-point numbers.

• Standard Library Functions:

  • Use of cmath for mathematical functions (e.g., floor, pow).

• Comments:

  • Importance of comments to clarify code without overusing them.

Fundamental Data Types in C++

• Built-in Types:
  • int, short, long, long long, float, double, char, bool.
  • Memory sizes and value ranges for each type.
• Data Conversion:
  • Narrowing conversions can cause data loss (use brace initialization to prevent errors).

Random Number Generation

• Use of rand() from cstdlib for generating random integers.
• Importance of seeding with srand() and using the current time for different results.
• Example: Rolling a dice program.

Conclusion

• Course designed to give a solid understanding of C++.
• Provides exercises to reinforce learning and build confidence.
• Encouragement for students to explore beyond the basics.
• Call to action: enroll in full course for in-depth learning.
