与C++输入流一样，输出流也可以使用输出流类的成员函数来实现数据输出。因此，在本小节中，将向用户介绍这些函数的原型及其使用方法等。

通常情况下，用户可以使用C++输出流类中的成员函数“put”将指定的数据放入到计算机输出流中，进行显示。该成员函数的原型如下所示：

01　　basic_ostream& put(E c) 　　　　　　　　　　//输出流类的成员函数原型

在成员函数“put”中，该函数的作用是将用户指定的数据放入到计算机的输出流中。该成员函数含有一个参数，即单字符类型。 -And C++ input stream, output stream can also use the output stream class member function to the data output. Therefore, in this section, the user will introduce the prototype of these functions and their use.

Under normal circumstances, the user can use the member functions in C++ output stream class "put" to the specified data into the computer output stream to be displayed. The member function prototype is as follows:

01 basic_ostream & put (E c) // output stream class member function prototypes

The member function "put", the function is user-specified data into the output stream of the computer. The member function contains a parameter that is a single character type.
