the value of '\0' =0,means the end of a string
the value of '0'=48, just means a char
you may test by follows:
#include <stdio.h>
#include <conio.h>
int main()
{
char c='\0';
printf("%d\n",c);
c='0';
printf("%d\n",c);
getch();
return 0;
}

'\0'一般是定义为字符串结束符号，是不能显示的，最为整数时是值为0，'0'就是字符 '0'，它显示时显示为一个字符'0' 它的字符编码不为0，故作为整数使用时不为0。
