什么更有意义 - char * string或char * string？ [英] What makes more sense - char* string or char *string?

问题描述

可能重复：

在C中，为什么星号在变量名称之前，而不是在类型之后？

我正在学习C ++，我遇到很多以null结束的字符串。这让我想，在声明指针时更有意义：

I'm learning C++ at the moment, and I'm coming across a lot of null-terminated strings. This has got me thinking, what makes more sense when declaring pointers:

char* string

或

char *string

？对我来说，char *格式更有意义，因为string的类型是一个指向char而不是char的指针。但是，我一般看到后者的格式。这也适用于引用。

? To me, the char* format makes more sense, because the type of "string" is a pointer to a char, rather than a char. However, I generally see the latter format. This applies to references as well, obviously.

有人可以告诉我后一种格式是否有逻辑原因？

Could someone tell me if there is a logical reason for the latter format?

推荐答案

在以下声明中：

char* string1, string2;

string1 是一个字符指针， code> string2 只有一个字符。为此，声明通常格式为：

string1 is a character pointer, but string2 is a single character only. For this reason, the declaration is usually formatted like:

char *string1, string2;

这使得更清楚的是 * 适用于 string1 ，但不适用于 string2 。好的做法是避免在一个声明中声明多个变量，特别是如果其中一些是指针。

which makes it slightly clearer that the * applies to string1 but not string2. Good practice is to avoid declaring multiple variables in one declaration, especially if some of them are pointers.
