头部进一步定义了这些(和一些其他)类型的最小值和最大值的宏:例如,INT_FAST_8_MIN和INT_FAST_8_MAX代表std::int_fast8_t。不过,获得这些值的标准 C++ 方法是使用下面讨论的<limits>工具。 算术类型属性<limits> std::numeric_limits<T>模板类提供了大量的静态函数和常量来获取数字类型T的属性。它专门用于所...

还有一点,对一个类的static member来说,指向它的指针只是普通的函数指针,不是pointer to class member,所以它的大小是4。5.指针运算符&和*它们是一对相反的操作,&取得一个东西的地址(也就是指针),*得到一个地址里放的东西。这个东西可以是值(对象)、函数、数组、类成员(class member)。其实很简单,房间里面...

Make sure that you #include <fstream>. Recall that ifstream is in namespace std, so you would need "using namespace std;" or "using std::ifstream" or explicitly write std::ifstream everywhere. Igor Tandetnik Tuesday, April 17, 2012 8:36 PM ...

If a user dislikes this practice of typedefing structs (which is fair, because it does have drawbacks - see below), they can always use the struct namespace instead. Only typedef structs; never basic types or pointers // Bad typedef double centermeters; typedef double inches; typedef struct...
Updated code to no longer use Scintilla namespace which has been removed from Scintilla.h Added a new member variable called "m_bCPP11Regex" which decides if Scintilla's support for C++11 regex should be used in the find / replace functionality. Thanks to Markus Nissl for suggesting this up...
