为了让您在使用数组，指针，结构，枚举，和不同的I/ O流的经验。为了让你有乐趣的应用程序是非常迷人的。

世界的简单的程序，我们将编写此项目模拟运行的生物围绕在一个简单的方形的世界。世界是一个m-n的平方二维网格（数m代表网格的高度的个数n表示宽度的网格。）。

每个生物生活的广场之一，面临的一个主要罗盘方向（北，

东，南，西），属于一个特定的物种，这就决定了该生物如何

行为方式。-To give you experience in using arrays, pointers, structs, enums, and different I/O streams.

To let you have fun with an application that is extremely captivating.

The simple world program we will write for this project simulates a number of creatures running

around in a simple square world. The world is an m-by-n two-dimensional grid of squares (The

number m represents the height of the grid and the number n represents the width of the grid.).

Each creature lives in one of the squares, faces in one of the major compass directions (north,

east, south, or west) and belongs to a particular species, which determines how that creature

behaves.
