1. In order to support the underlying programming, C + + defines some inherent non-portable features, the so-called non-portable feature refers to a machine-specific feature.2. A bit field contains a certain number of bits, and the layout of the bit

A container is a collection of certain types of objects. Sequential containers (sequential container) provide us with the ability to control the order in which elements are stored and accessed. This order does not depend on the value of the element,

In network programming, the special characters contained in the URL parameter need to be replaced with "%20" by the two-bit hexadecimal method of the ASCII code, which is converted to a character that the server can recognize, such as a space ASCII

Why use const? Code written with symbolic constants is easier to maintain, and pointers are often moved by reading edges rather than writing edges; many function references are read-only. The most common use of const is as an array of bounds and

The following excerpt from the Wikipedia "http://zh.wikipedia.org/wiki/Luhn%E7%AE%97%E6%B3%95" Luhn algorithm (Luhn algorithm), also known as the "modulo" (Mod 10) algorithm, is a simple checksum algorithm, generally used to verify the

The transfer of parameters is generally divided into two types: one is "value passing" i.e. a copy of the passed argument, and since it is a copy, any action on the parameter in the function will not be reflected in the original argument. The other
