RAII Pattern: Automatic resource management

1h 2min

Intermediate

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

15min

Intermediate

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

17min

Intermediate

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.

Class Templates: Generic class design

8min

Intermediate

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

15min

Intermediate

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. 

Video

Concepts (C++20): Template constraints

1h 11min

Intermediate

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).

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

15min

Intermediate

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.
