1) 能用#define 来改变变量或function名字吗?比如:
#define X 1
然后用类似如:int aX;
其实是想得到: int a1;
2) #define 能嵌套吗?比如:
#define a #define b 1
然后用
a
其实想得到:
#define b 1
上面两个例子都不对,但能可行吗?

(CNSNews.com) – U.N. Secretary-General Ban Ki-moon addressed the advisory
board of a newly-established U.N. Counter-Terrorism Center in Saudi Arabia
on Sunday but was silent on the world body’s enduring failure to come up
with a universal definition of terrorism.
For well over a decade, the biggest single obstacle preventing a U.N.
agreement on defining terrorism has been the insistence by Muslim states

For example, for tables A, B with Name, ID
I want to
select A.Name
from A, B
where A.Name = B.Name
but here the = is not strict equal. They are seen to be equal if these two
strings A.Name and B.Name are different with at most 1 character. For
example, 'John' and 'Johnn' are equal.
Is there any way to define a function to deal with this? Can I define a
function else where to define this equal, than then use it after "where"?

this implementation smwhere in their code. If part of the code of two
different derived classes is similar then it makes sense to move it up in
the hierarchy, even if the function should be pure virtual.

you can ONLY define window size for new window.
you write a javascript function to open this window.
on your original page, you either use onLoad to
call this function (which means the new window with
your specified size will open right after a user
open your original page), or call this function
when the user click on one of the links in your
original page.
you can't define window size for a window opened
by the user him/herself.

问题是,我有header guard,那么这个header的实际内容(也就是#ifndef #define 和

function也只被define了一次啊
declare可以多次?应该也只能一次吧,完全一样的函数重复声明编译就会有错误
名词使用问题我改改吧,应该叫做function template比较确切,我是自己看C++ primer学的

因为C/C++compiler不能保证同一个头文件不被包括一次以上,所以码工需要多写几
行#define. 这种基本上成了标准写法

#define XXXXX
头文件的内容

对XXXXX的要求只需要独特即可。当然要满足identifier的条件。
