我实在是不写不出来啦，研究了两天了，
void del_substr(char *str,char const *substr)

{
        while(*str)
        {
            if(*str==*substr)
            {
                while(*str)
                {
                    *str=*++str;
                }
            }
            if(*str=='\0'&&*substr=='\0')
                return;
            str++;
            substr++;
        }
}
越写越不像啊
