This time I’ll cover Back References, Substitutions, Look Ahead, Or Conditionals and 3 problems for you to solve. All of the heavily commented code follows the video below. Use it to receive the best results in your studies. Continue reading C++ Tutorial 21 →

In this part of my C++ tutorial I continue showing tons of examples about regular expressions. If you missed the 1st part watch it first.

This time I’ll show more ways to match what you are trying to grab. We’ll also talk about Greedy vs. Lazy matching, Boundaries, and grabbing multiple subexpressions. This tutorial also contains 2 problems for you to solve. All of the code follows the video below to help you learn. Continue reading C++ Tutorial 20 →

In this part of my C++ tutorial I’ll start covering Regular Expressions. There are tons of examples and a problem for you to solve. I’ll cover how to search and then cycle through matches. We’ll look into cycling through matches with an iterator. Then we’ll create numerous regular expressions to get just that exact data we need and output or replace it.

All of the heavily commented code follows the video below. Feel free to do what ever you’d like with it. Continue reading C++ Tutorial 19 →

In this tutorial I’ll cover the Associative Containers, Set, Multiset, Map, and Multimap. I’ll also cover the Container Adapters : Stacks, Queues, and Priority Queues. And, finally we’ll explore enums.

Like always all of the heavily commented code follows the video below. Use it while watching the videos for best results. Feel free to do what ever you’d like with it. Continue reading C++ Tutorial 18 →

In this part of my C++ tutorial I’ll cover Sequence Containers which contain data that is stored in order. Previously I covered Vectors and will now cover Deques, Lists and Forward Lists.

I’m getting near the end of my core coverage of C++. Once I finish I will then move on to GUI development, Algorithms and all the other things that have been requested. All of the code follows below. Continue reading C++ Tutorial 17 →

In this part of my C++ Tutorial I’ll be focusing on Threads. We’ll cover how to create, pause, and pool threads. We will then compare how long it takes to generate a list of prime numbers with and without threads. Also we’ll check out many ways of working with time.

Like always the heavily commented code follows the video below. Feel free to do whatever you’d like with it. Continue reading C++ Tutorial 16 →

In this part of my C++ tutorial I will answer a bunch of questions I have received. I’ll talk about allocating memory with malloc(), Smart Pointers, Regular Pointers, Deallocating Memory, unique_ptr, Difference Between /n and endl, Polymorphic Templates and a whole bunch more.

Like always the heavily commented code follows the video below. For best results print it out and take notes as you watch. Continue reading C++ Tutorial 15 →

In this tutorial I cover many topics many people have asked for. I show how to include outside files, Preprocessor Directives, Macro Constants, Macro Functions, Template Functions, Template Classes, and Iterators.

Like always all of the code follows the video below. It is heavily commented and it is recommended to print it out and take notes on it as you watch. Continue reading C++ Tutorial 14 →

In this tutorial we explore advanced uses of functions using C++. We’ll cover how to store functions as variables, pass functions into other functions, store functions in a vector and more. Then we’ll solve 2 problems. We’ll receive lists of numbers and then return a list of only the odd values. We’ll then generate random lists of heads and tails and add up how often each occurs. All of the code and a transcript of the video follows below. Continue reading C++ Tutorial 13 →

In this part of my C++ tutorial we’ll cover Operator Overloading, File I/O and will present you with another problem to solve. We’ll learn to use unary and Binary operators. We’ll specifically overload ++, print customer strings, +, [], ==, <, >, and =. Then we’ll write and read from files.

All of the code and a transcript follows the video below. I hope you enjoy the tutorial. Continue reading C++ Tutorial 12 →

We cover a lot in this tutorial. We cover Polymorphism, Structs, Friend Classes, Abstract Classes, Override, Final, Virtual and much more.

All of the code used follows the video below. For best results print it and take notes as you watch. Please leave any questions that you have. I hope this tutorial clears up Polymorphism for everyone. Continue reading C++ Tutorial 11 →

I was asked to put all 25 C# videos on one page with a description of each video, so I thought I would. I covered just about everything you’d ever want to learn about C# in this series. I cover the core language, OOP, Generics, LINQ, Threads, File I/O, Serialization, WPF, XAML, Document API, Databases and even make a full Paint application.

A link to all the code from every video follows the video below with a description. Continue reading C# Tutorial Series →

I’m finally covering Object Oriented Programming with C++! I cover classes, objects, public, private, protected, constructors, deconstructors, pointer operator, dot operator, getters, setters, super classes, inheritance, calling super class functions, overwriting functions, and much more.
