/* Simulation of Conway's game of Lif on a bounded grid
Pre: The user must supply an initial configuration of living cells.
Post: The program prints a sequence of maps showing the changes in the configuration of living cells according to the rules for the game of Life.
Uses: functions Initialize,WriteMap,NeighborCount,and UserSaysYes */

问一下前面两行
#include"common.h" /* common include files and definitions */
#include"life.h" /* Life's defines,typedefs,and prototypes */
这个文件从哪来,怎么用上去?

common.h文件主要包括如下内容：
#include<stdio.h>
#include<stdib.h>
typedef enum Boolean{FALSE,TRUE}Boolean;
void Error(char*);
void Warning(char*);

life.h:
......
......
只是想知道如何使用这两个文件！！在主程开头写这些程序？？
