In the last part of my C Video Tutorial, I covered how to convert from base 10 to base 2, base 8 and base 16 with C.
At the end of that tutorial, I provided a homework assignment for you to write code that converts from any base back to base 10. In this tutorial, I will walk through exactly how to do that.
You can find all of the code below the video. Please leave any questions you may have. Continue reading C Video Tutorial 14
Welcome to part 13 of my C Video Tutorial. I have been asked many times to explain how to convert base 10 numbers into binary (Base 2), octal (Base 8) and hexadecimal (Base 16) numbers. Today I’ll cover that topic.
I also cover how the different numbering systems work so that it will be easy to work with them in the videos that follow. All of the code can be found below along with a transcription to aid in translation. Continue reading C Video Tutorial 13
Welcome to my C Binary File IO tutorial. With the binary view of a file you have access to all the bytes in the file. You can store strings, arrays, structs, etc.
Aside from showing how to save and retrieve strings, I’ll also cover how to save array data and grab it out of the file randomly. I also briefly cover error handling in C. All the code is available below along with a transcript of what I said for translation. Continue reading C Video Tutorial 12
In this part of the C Video Tutorial I will provide C File IO examples. I’ll cover C Text File IO in this tutorial and the Binary File IO functions in the next part.
I specifically cover the following topics: FILE Data type, fopen(), fputs(), fseek(), ftell(), fgets(), fclose(), fscanf(), puts(), fprintf(), Different Ways to Access Files, and more. All of the code used is available below the video. Continue reading C Video Tutorial 11
In this video I continue with my C Linked List tutorial. In part 9, I gave you homework and in this video I will show you my answer. You guys asked for more tutorials like this, so I’m giving it a try.
So, today I’ll show you how to search through a Linked List. I’ll also cover how to delete structs and remove them not only from the Linked List, but also from memory. All of the code from the video is below along with a transcription. Continue reading C Video Tutorial 10
Welcome to my linked list structure or linked list struct tutorial. I have been asked to cover these structs numerous times lately and so I will do so.
In this tutorial and the next I will show how to create an unlimited number of structs using malloc. I’ll focus on creating the structs, adding them to the list and then how to display them. Because you guys ask for homework all of the time, you’ll then get the opportunity to write the code on how to search through the linked list, how to delete structs and free memory. Continue reading C Video Tutorial 9
Welcome to part 8 of my C Video Tutorial. In this video I cover a topic I have received many requests for. This is basically a C Malloc Tutorial.
Malloc() ( Memory Allocator ) is used to dynamically set aside memory at run time. Because malloc() returns a pointer to that location in memory it can be a bit confusing. I’ll cover how to store both regular data types as well as structs using malloc(). Continue reading C Video Tutorial 8
In the past week I have been asked a countless number of times how to install GCC ( GNU Compiler Collection ). I have been using it in my C Video Tutorial.
I show you how to install GCC on Windows as well as on a Mac in the video below. Not only did I make a video, but I also have everything listed step-by-step below after the video. If you have any trouble setting this up, leave a comment below and I’ll try to help. Continue reading How To Install GCC

I’m also going to experiment with a new style that is more interactive and I hope it feels more like a classroom setting. Throughout the tutorial I will constantly insert brain teasers. Hopefully they aren’t distracting. I do this every once in a while to try and improve. Continue reading C Video Tutorial 6
Today I’m going to cover how to create and use a struct in C. Structs are used when you need more then one piece of data to describe one thing. You can’t use an array because an array only holds data with the same data type
I’ll specifically cover how to : Create a Struct, Get data from a Struct, Initialize a Struct, Pass a Struct to a Function, Use Typedef, Change a Value in a Struct, Use a Struct in a Function, ->, *(structName) and how a Struct is stored in memory. The code follows the video below. Continue reading C Video Tutorial 5
Welcome to part 17 of my Android Development Tutorial. This is part 2 of my Android Fragments Tutorial series. Part 1 is here and you should watch it before watching this video.
Fragments are often used so you can create completely different interfaces depending upon the screen real estate available. We’ll cover how to do that and we’ll also look at how we can get the fragments to communicate with each other and the main activity. The Whole package is available here Android Fragments. Continue reading Android Development 17
Welcome to part 16 of my Android Development Tutorial, or maybe I should call this one an Android Fragments Tutorial!
There has been a ton of demand for an Android fragments tutorial, so I wanted to try and do it right. It is very easy to get confused by fragments if they aren’t presented in the right way. I did my best to cover a lot in this video and most importantly to keep it simple. If you understand fragments you’ll be able to make great interfaces. Don’t worry I’ll cover everything in future tutorials. Continue reading Android Development 16
