问题描述

在Pascal中的

关键字可以用来快速访问记录的字段。
任何人都知道C ++是否有类似的东西?



例如:
我有一个指针有许多字段,我不想类型像这样:

  if(pointer-> field1)&& (pointer-> field2)&& ...(pointer-> fieldn)

我真正想要的是这样的C ++:

  with(pointer)
{
if(field1)&& (field2)&& .......(fieldn)
}


解决方案>

在C ++中,您可以将代码放在由指针引用的类的方法中。在那里你可以直接引用成员而不使用指针。让它 inline ,你几乎可以得到你想要的。


with keyword in Pascal can be use to quick access the field of a record. Anybody knows if C++ has anything similar to that?

Ex: I have a pointer with many fields and i don't want to type like this:

if (pointer->field1) && (pointer->field2) && ... (pointer->fieldn)

what I really want is something like this in C++:

with (pointer)
{
  if (field1) && (field2) && .......(fieldn)
}

解决方案

In C++, you can put code in a method of the class being reference by pointer. There you can directly reference the members without using the pointer. Make it inline and you pretty much get what you want.
