char * a声明指向字符串的指针。因此，要说char * a =这是

一个字符串，将字符串的第一个字母的地址放入

指针a。所以，首先是t。位于内存的某处，

指针包含地址。

char *a declares a pointer to a string. So, to say char *a = "this is
a string", puts the address of the first letter of the string into the
pointer a. So, that first "t" is located somewhere in memory, the
pointer a contains the address.

char * a ="这是一个字符串" ;;

char *a="this is a string";

如果你写了printf（" char =％d"，a）;你会看到地址

其中a已存储

如果你写了printf（char =％c，* a）;你会看到该地址有什么价值

。

If you wrote printf("char = %d",a); you would see the address
where a has been stored
If you wrote printf("char = %c",*a); you would see what value was
at that address.

" char * a ="这是一个字符串"

这里是字符串文字"这是一个字符串存储在数据中

segment&你正在使指针变量a指向这个位置

但是a可以更改为指向程序中的任何其他位置。


char a [] ="这是一个字符串" ;;


但是在这里你不能改变变量a的指针。到程序中的其他

位置。


i希望这对你有帮助....


jeniffer写道：

"char *a="this is a string"
Here the string literals " this is a string " is stored in data
segment & you are making pointer variable "a" to point this location
but "a" can be changed to point to any other location in a program.

char a[]="this is a string";

but here you can''t change pointer of the variable "a" to other
location in the program.

i hope this help you....
