#include <reg51.h>
#include <stdio.h>
//unsigned char code *workState[] = {"工作正常…… ",
// "等待关机…… ",
// "可以关机。 "};
unsigned char code *workState[] = {"Follow me",
"how are you",
"telephone to me"};
//然后提示有错误：
//CCS812.C(20): error C243: 'array[]': string out of bounds
//这是为什么呢？
//在程序中我是这样使用的：
//unsingned char string[];
//string[]=workState[1];
//……
//是否是我的调用有问题？？？还请各位大侠多多帮忙～～～～谢谢先～～～～
