C++

First, briefIn the C language family program, the header file is used extensively. In general, each C++/C program typically consists of a header file and a definition file (define files). A header file is a carrier file that contains function

a bidirectional queue is similar to a vector, but it allows for quick insertion and deletion of the container's head (as in the tail). Constructors Create a new bidirectional queue Operators Comparing and

C + + Bitsets provides programmers with a data structure for a bit set. Bitsets uses many two-dollar operators, such as logic and, or so on. Constructors Create a new Bitsets Operators Compare and assign Values

The Vectors contains a series of continuously stored elements that behave in a similar array. Accessing any element in the vector, or adding elements from the end, can be done in constant-level time complexity, while the element looking for a

A collection (set) is an associative container that contains sorted objects Begin () Returns an iterator that points to the first element Clear () Clear all elements Count ()

the library automatically defines some standard objects: cout, an object of the Ostream class that can display data on a standard output device. Cerr, another object of the Ostream class, outputs data to the standard error output

A two-dimensional array consists of several one-dimensional arrays.In C + +, a one-dimensional array of two-dimensional arrays must be equal in length. In C #, they can be unequal.C # Two-dimensional arrays are:1, normal two-dimensional array:int
