指针的两种不同类型的星号位置? [英] Two different types of asterisk locations for a pointer?

问题描述

说你有这个..

 int fry = 50;

现在创建一个指针并引用该值，可以通过两种不同的方式放置星号:

Now wen making a pointer and referencing the value, the asterisk can be placed two different ways:

 int* d1 = &fry;

还有……

 int *d1 = &fry;

我想知道有什么区别以及最好在什么情况下使用它们?谢谢！

I was wondering what the difference is and what situation it would be best to use each? Thanks!

推荐答案

没有区别.你甚至可以做 int*d1 和 int * d1.

There is no difference. You can even do int*d1 and int * d1.

在我看来，你应该更喜欢 int *d1:这个选择在避免混淆方面有特别的作用:

In my opinion, you should prefer int *d1: this choice has particular utility in avoiding confusion:

int* d1, d2;
int *d1, d2;

这些语句都声明了一个整数和一个指向整数的指针.第一个版本看起来很误导.

These statements both declare one integer and one pointer-to-integer. The first version looks quite misleading.
