void my_strlen( char *str)
{
        int count=0;
        while(*str!='\0')
        {
                str++;
                count++;
        }
        printf("%d\n",count);          
}

int main()
{
        const char arr[]="hello bit";
        my_strlen(arr);                
        return 0;
}

函数调用时不是只传值嘛，上面这段程序为啥有编译错误，而下面这段就没事：

void my_strlen( const char *str)
{
        int count=0;
        while(*str!='\0')
        {
                str++;
                count++;
        }
        printf("%d\n",count);          
}

int main()
{
        char arr[]="hello bit";
        my_strlen(arr);                
        return 0;
}
