Description
Defines the Point class in a two-dimensional plane. The data member in the class is the coordinate of the point, and then defines the membership function dist () to calculate the distance between two points.
Complete the following procedures 1 and 2.
Procedure 1:

Requirements:
Understanding C ++ stream operation functions
Understanding the two methods of I/O Stream format Control
Basic output stream (cout) Operations1. Use the stream insertion operator (# Include Void main (){Char C [] = "good morning ";Cout }Running result:Good morningPress any key to continue2. Use member functions// Ostream put (char );// Output one character for continuous use# Include Void main (){Cout. Put ('A'). Put ('\ n ');}Running result:APress any key to continue// Ostream
The simplest Recursion Method: (this algorithm times out .)

Next, we will learn about the status of the input/output of the relevant knowledge, C + + responsible for the input/output system includes the results of each input/output operation of the record information. These current state information is contained in an object of type Io_state. Io_state is an enumeration type (just like Open_mode), and here is the value it contains.

The function froop() expects to is called with one argument, which'll be double is type, and that the function would return a T Ype int value. For instance, it could is used as follows:int gval = froop(3.14159);The function has a rattle() no return value and expects an int argumen

The input of the string has 6 in the way, these six ways each have each characteristic, I this study note is own experience summary, did not discuss the memory, the function library and so on the complex question, only is for the practical:First: CINCIN accepts one character at a time, so some people choose to define a character array and then enter it with the CIN loop, but the limitation of CIN is that it

Using std: map; // using namespace std;
1) map constructor map provides a total of six constructor functions, which involve the memory distributor. I will skip this article. Below we will be exposed to some map constructor methods, we usually construct a map using the following method:
map
mapStudent;
2) data insertion
After constructing the map container, We can insert data into it. Here are three data insertion methods:
A) insert pair data using the insert function

1. introduce several common functions first
1) getline (istream is, string s) stores the characters read from the input stream is \ n, or the end of the file or reading errors. It is equivalent to reading a line of characters into s.
2) getline (istream is, string s, char c) stores the characters read from the input stream is always ended with c, or the end of the file or the reading error) in string s.
For example, getline (cin, str ,'#')
3) getchar
