C++ Game Development Cookbook

Overview of this book

C++ is one of the preferred languages for game development as it supports a variety of coding styles that provides low-level access to the system. C++ is still used as a preferred game programming language by many as it gives game programmers control of the entire architecture, including memory patterns and usage. However, there is little information available on how to harness the advanced features of C++ to build robust games. This book will teach you techniques to develop logic and game code using C++. The primary goal of this book is to teach you to create high-quality games using C++ game programming scripts and techniques, regardless of the library or game engine you use. It will show you how to make use of the object-oriented capabilities of C++ so you can write well-structured and powerful games of any genre. The book also explores important areas such as physics programming and audio programming, and gives you other useful tips and tricks to improve your code. By the end of this book, you will be competent in game programming using C++, and will be able to develop your own games in C++.

Using bit fields in a struct

In structures, we can use bit fields to denote what size we want the structure to be. As well as this, it is also important to understand what size a struct actually takes.

Getting ready

You need a Windows machine and a working copy of Visual Studio. No other prerequisites are required.

How to do it…

In this recipe, we will find out how easy it is to use bit fields to find the size of a struct. Add a source file called Source.cpp. Then add the following code to it:

#include <iostream>

struct Type
{
  int a;
  unsigned char c[9];
  unsigned  b;
  float d;

};

struct Type2
{
  int a : 2;
  int b : 2;
};
int main()
{
  std::cout << sizeof(Type)<<std::endl;
  std::cout << sizeof(Type2);

  int a;
  std::cin >> a;
}

How it works…

As you can see, in the example we have assigned a struct of int, a char array, an undefined unsigned variable, and a float. When we execute the program, the output should be the size of both the structures...
