这篇博文是基于凌明老师的嵌入式系统高级C语言做的课程笔记。同时结合自身工作经验将一些C语言的用法实例化，加深自己对C语言的理解。亦方便自己复习。同时摘有K&R版本C语言的部分笔记

Pointers and Arrays
A pointer is a variable that contains the address of a variable.
some complicated Declarations:
char **argv;
//pointer to pointer to char
int (*daytab)[10];
// pointer to array[10] of int
int *daytab[10];
//array[10] of pointer to int
void *comp;
//function returning pointer to void
void (*comp)();
//pointer to function return void
Structure
A structure is a collection of one or more variables, possible of different types, grouped together under a single name for convenient handling.
Pointers to structure are so frequently used that an alternative notation is provided as a shorthand. If p is a pointer to a Structure, then
p->member
struct {
int len;
char *str;
}*p;
++p->len;
//increments len , not p, because the implied parenthesization is ++(p->len)
(p++)->len;
//increments p afterward
