变量初始化/我是一个n00b [英] variable initialization / I'm a n00b
问题描述
大家好 - 这是我在这里的第一篇文章 - 只是一个简单的问题：
#include< math.h>
double foo = cosh （0.621）;
int main（）{
返回0;
}
失败与
错误：初始化元素不是常数
除了告诉我我做错了什么之外，请你参考
我对相关问题的适当参考？我一直在做
我的阅读（开网+野生动物园书架），但我不知道在哪里看b $ b。即使我必须（感叹）买书，我也会感激你的
指针。
谢谢和问候，
罗斯
Hi all- this is my first post here- just a quick question:
#include <math.h>
double foo = cosh(0.621);
int main() {
return 0;
}
fails with
error: initializer element is not constant
In addition to telling me what I''m doing wrong, could you please refer
me to an appropriate reference for related questions? I''ve been doing
my reading (open net + safari bookshelf), but I don''t know where to
look. Even if I have to (sigh) buy a book, I would appreciate your
pointers.
Thanks and regards,
Ross

是吗？静态持续时间对象的初始化程序（即全局对象，
和您使用静态声明的本地对象）必须是编译时
常量，函数调用不是编译时常量，即使
所有参数都是。
Yes? Initialisers for static-duration objects (i.e., "global" objects,
and "local" objects you''ve declared using static) must be compile-time
constants, and a function call is not a compile-time constant, even if
all its arguments are.
除了告诉我我做错了什么，请你参考

" K& R"是C编程语言。作者：Brian Kernighan&丹尼斯
里奇。 Ritchie是C的发明者，这是关于该语言的最终
书。如果你已经熟悉了一般的编程，那么它就是开始学习C的好地方。如果不是b $ b，那么有些书更适合初学者。

book on the language. If you are already familiar with
programming in general, it''s a good place to start learning C. If
not, there are books better oriented to beginners.
K& R在半年前不再是C上的权威工作，大约十七美元。尽管如此，阅读比最近的权威作品更好。
