IEEE754 Standard, floating-point memory layoutThe following is only described by float (4 bytes in memory, 32bits), double (8 bytes, 64bits) in the same vein, only slightly different.The memory distribution of floatIEEE754 Specifies that 32bit float

//article 07: Declaring a virtual destructor for a polymorphic base class//1. The destructor of the destructors class is not defined as a virtual function, because a pointer or reference to a base class can point to an object of the derived class,

The constructor can not be a virtual function, this is obviously, after all, virtual functions are corresponding to a virtual function table, virtual function table is the existence of object memory space, if the constructor is virtual, you need a

I. C + + class reference members, constant members of classes, initialization of static members of a classThe reference member and constant member initialization of the class are placed in the initialization list, because initialization is only one

STL provides a set of templates that represent containers, iterate over them, function objects, and algorithms. A container is a cell that is similar to an array and can store several values. STL containers are homogeneous, that is, the type of

A smart pointer is a class object that behaves like a pointer, and there are other functions for this object alone. This section describes three smart pointer classes that can help you manage dynamic memory allocations. Let's take a look at what
