临时局部变量的命名规则 [英] naming convention of temp local variables
问题描述
什么是命名的本地功能的临时变量的标准方法是什么?让我给你的,我做的事情的说明。我得到一个指向结构的指针,所以我想存储其成员之一在本地,以避免解除引用,然后再进行任何修改分配回指针。
What is the standard way to name a temp variable in the local function? let me give you an illustration of what I am doing. I get a pointer to a structure, so I want store one of its members locally to avoid a de-referenced, and then any modification assign back to the pointer.
要更具体:
struct Foo
{
double m_d;
};
void function (Foo* f)
{
double tmp=f->m_d;
/***Other stuff***/
f->m_d=tmp;
}
我不喜欢 TMP 。如果我有很多人在一个函数,他们只添加混乱。
I don't like tmp. If I have many of them in a function, they only add a confusion.
感谢

Linus Torvalds公司 - Linux内核编码风格从Linus Torvalds公司:
Linus Torvalds - Linux Kernel coding style from Linus Torvalds :
本地变量名应该简短,并以点。如果你有
一些随机整数循环计数器,它或许应该被称为I。
称之为loop_counter是非生产性,如果没有它的机会
是错误的理解。同样,tmp可以作为几乎任何类型的
变量用于保持临时值。
LOCAL variable names should be short, and to the point. If you have some random integer loop counter, it should probably be called "i". Calling it "loop_counter" is non-productive, if there is no chance of it being mis-understood. Similarly, "tmp" can be just about any type of variable that is used to hold a temporary value.
如果你怕混淆了你的本地变量名,你有另一个
的问题,这就是所谓的函数增长激素失调综合征。
If you are afraid to mix up your local variable names, you have another problem, which is called the function-growth-hormone-imbalance syndrome.
