Skill objectives

Chapter 01

Memory Management

Master modern C++ memory safety through smart pointers and RAII patterns, eliminating memory leaks while building robust, production-ready applications.

Skills: C++, Technical Communication

RAII Pattern: Automatic resource management

RAII, or "Resource Allocation is Initialization," is one of the cornerstones of C++. What is it, why is it important, and how do we use it in our own code.

Memory Leaks: Detection and prevention

A memory leak happens when a program allocates memory from the system but fails to release it after it’s no longer needed. Over time, this unreleased memory accumulates, reducing the available memory for other processes and potentially degrading performance or causing crashes.

Stack vs Heap: When to use what

In this step we will go through the concept of dynamic memory allocation in c or c++ and explained how memory is managed for an application.

Chapter 02

STL (Standard Template Library)

Leverage the power of STL containers and algorithms for efficient data manipulation, understanding performance implications and choosing optimal solutions.

Skills: Technical Communication, C++

Video32min

Containers: vector, array, map, list, set, unordered_map, deque

Containers provided by the standard library in C++ have almost become as essential as the language keywords themselves.

STL Algorithms: sort, find, transform, for_each

105 algorithms that the STL currently has, including those added in C++11 and C++17. The point of this presentation is to highlight the different groups of algorithms, the patterns they form in the STL, and how the algorithms relate together.

Chapter 03

Templates and Generic Programming

Create flexible, reusable code through template programming, mastering function templates, class templates, and modern C++20 concepts for type-safe generics.

Skills: C++, Technical Communication

Video18min

Function Templates: Creation and specialization

What is a template, template parameter and arguments. 

Video8min

Class Templates: Generic class design

In this chapter we'll go through the need to create a different class for each data type OR create different member variables and functions within a single class. In Class Templates We write a CLASS that can be used for different data types.

Template Meta-Programming

Template meta-programming (TMP) refers to uses of the C++ template system to perform computation at compile-time within the code. It can, for the most part, be considered to be "programming with types" — in that, largely, the "values" that TMP works with are specific C++ types.

Concepts (C++20): Template constraints

Basic topics of generic programming using concepts to write constrained templates, overloading constrained functions (why, when, and how), and how to define good concepts (which is a bit trickier than you might imagine).

Chapter 04

Advanced Object-Oriented Programming

Explore sophisticated OOP concepts including multiple inheritance, polymorphism, and move semantics to build scalable, maintainable object hierarchies.

Skills: C++, Code Review

Multiple Inheritance: virtual inheritance and abstract classes

Multiple inheritance exploration covering virtual inheritance solutions, abstract classes, interface segregation principles, and practical safe usage patterns for C++ developers.

Polymorphism: Virtual Functions and Dynamic Dispatch

Virtual functions enable polymorphism through dynamic dispatch: runtime determines which derived class method to call based on object's actual type.

Chapter 06

C++ Comprehensive Guide

This is a set of core guidelines for modern C++ (currently C++20 and C++17) taking likely future enhancements and ISO Technical Specifications (TSs) into account. The aim is to help C++ programmers to write simpler, more efficient, more maintainable code.

Core Guidelines

The guidelines are focused on relatively high-level issues, such as interfaces, resource management, memory management, and concurrency. Such rules affect application architecture and library design. Following the rules will lead to code that is statically type safe, has no resource leaks, and catches many more programming logic errors than is common in code today.
