Wrote a simple program, but given that there is some information that needs to be printed on the console, just like the information displayed by the console when you launch Apache Tomcat on Windows. After a while, the printf was encapsulated,

Class inheritance is statically defined at compile time and can be used directly, and class inheritance can easily change the implementation of the parent class. But class inheritance also has some shortcomings. First, because inheritance is defined

First, what is byte alignment?The memory space in modern computers is divided by byte (byte), in theory, it seems that access to any type of variable can start from any address, but the reality is that when accessing a particular variable, it is

The array realizes the double-ended queue when the difference between the overflow and the underflow is observed.Implementing a queue with two stacks is equivalent to putting two stacks together (back-to-back), one stack for the queue, and one stack

C + + contains an STL (Standard Template Library), which is what we often call the C + + templates Gallery, also known as C + + generic library, which he named in StdSome of the data structures and algorithms that we commonly use are very handy for

1. General function Variable parameter templateFor some time, we can not know exactly, when the number of parameters of the function, but do not want to use too much so-called function overloading, then you could emulate the following

Access control for 6.2.6 class membersClass members include member variables and member functions of the class, which are used to describe the properties and behavior of the class, respectively. The access control of a class member determines which

Const can limit the value of a variable not allowed to be changed, using the const to some extent can improve the security and reliability of the programconst int a = 10;The value of variable a cannot be modified, it is always the initial 10int

In our own applications, custom types of files are often used to store data related to the application, such as the. osf file, which is the application's project file. If the file type is not registered with the Windows registry, then. The icon for
