Character data is a simple character under the 16-bit Unicode standard.
The minimum value is: ' \u0000 ' (or 0).
The maximum value is: ' \uffff ' (or 65,535).
Character data can be used to store any letter.
For example: Char letter A (character type a) = ' a '

Although R is object-oriented, I personally think that the so-called objects in R are only a structure (struct ). You still need to use the function to operate it.
The data structure in R is mainly oriented to some concepts in linear algebra, such as vectors and matrices. It is worth noting that there is actually no simple

asynchronous call process, the asynchronous call model provided by ASP. NET Ajax contains support for passing user context. Through the user context object, we can easily access the state in the original call function. This chapter also describes how to implement these functions.

All ordered types (except set and Frozenset types) support access to objects of the given order. In contrast, the mapping container is used to hold objects that are not very sensitive to the order, and you can extr
