The container is the place where the data is stored.The STL (Template Library) for C + + has two types of containers: sequential containers and associative containers. Simply put, a sequential container aggregates a single type of element into a

I. Arrays and collectionsArrays: can store any number of data of the same typeData item: Same type① Each data type has a number (index or subscript)The index of the ② data (subscript) is a number of type int③ starts at 0 and sequentially numbers

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
