将全局变量赋予函数 [英] Paasing global variables to functions
问题描述
大家好
在很多地方我都看到程序员将全局变量
传递给c中的函数。我无法弄清楚他们为什么会这样做。需要
这方面的一些线索。在某个地方，我听说这个哲学来自
对象的世界，但它是否适用于c？
Hi all
At many places I have seen that programmers pass global variables
to functions in c. I am not able to figure out why they do so. need
some clues on this. somewhere i heard that this philosophy is from
object orieted world but is it applicable for c?

永远不要低估盲目愚蠢的压倒性力量。

Never underestimate the sheer overwhelming power of mindless stupidity.

例如，该函数被多次调用不同的
参数比特定的全局变量。例如：
f（myglobal）;
f（mylocal）;
f（myglobal2）;
for instance, the function is called multiple times with different
arguments than that specific global variable. eg:
f(myglobal);
f(mylocal);
f(myglobal2);

听起来很奇怪。如果一个变量有一个全局范围，它就不一致了
将它传递给一个函数（通过参数，我猜）......
也就是说，更好地避免全局范围变量...

Sounds weird. If a variable has a global scope, it''s inconsistent to
pass it to a function (via a parameter, I guess)...
That said, better to avoid global scope variables at all...
