CIN is a standard input stream object in the C + + programming language, that is, an object of the IStream class. CIN is mainly used to read data fro

C/C ++ input/output
I. Cin> when a space or line break '\ n' is encountered, the input ends.
This operator reads data based on the type of the following variable.
Enter the end condition: Enter, Space, and Tab are displayed.
Processing of Terminator: discards the terminator (Enter, Space, Tab) that ends the input in the buffer)
#include
[Analysis] When a string is read for the first time, spaces are stopped. abcd is read into str1, spaces are discard

S. Good () if the stream is in the valid state, this function returns true
S. Clear () reset all statuses in stream s to valid
S. Clear (FLAG) sets the status of a specified condition in the stream to valid.
S. setstate (flat) adds a specified condition to S. The flag type is STRM: iostate.
S. rdstate () returns the current condition of stream s. the return value type is strm: iostate.

Cin, cout, and cerr are the most basic input and output streams. They are operated by the operators "
For example, read two strings from the keyboard and then merge them into the output
string s1,s2;cin>>s1>>s2;cout
Run the following input:
Hello
Keambar
implement in other languages.
C + + input cout and output cininput and output are not formal components of the C + + language. Neither C nor C + + itself provides a specialized statement structure for input and output. The input output is not defined by C + + itself, but is defined in the I/O library provided by the compilation system.
The output and input of C + + is implemented in the form of "stream".
Information about the definition of CIN,

Key = nullkey){HT [Key]. Key = key;HT [Key]. Next = em;}Else if (HT [Key]. Key = Key) // if a conflict occurs, use the link address to resolve the conflict.{P = HT [Key]. Next;While (p-> next! = NULL) // find the insert position and insert it to the end of the table Synonym{P = p-> next;}P-> next = em;}Return 1;}
Tips for C ++ Primer Chapter 8, primerchapterChapter 1 IO library types and header files
Header file: Class
Iostream (read/write stream): istream ostream iostream
Fstream (read/write file): ifstream ofstream fstream
Sstream (read/write memory string object): istringstream ostringstream stringstream
PS:
Ifstream and istringstream inherit from istream;
Ofstream and ostringstream inherit from ostream;
Generally, a derived class object can be used as its base class object. For example, you can use
as the endl tag.
B. the stream is out of scope, so it is revoked.
C. Corresponding input stream request input (that is, cout will refresh the output when using cin input ).
D. The stream buffer is full.
E. explicitly tell the stream to refresh the output buffer. Is the flush () method.
Cout
Cout. flush ();
Not all output streams are buffered. For example, the cerr Stream does not buffer its output.
Handle output errors: output errors may b

Recently, in order to allow the Godaddy server to support magento, I have to install the mcryptmodule. By the way, I can also install a piece of warningmessage during phpmyadmin logon. Linux prawns don't laugh at me. I 've been busy for a long time. For me, Windows is very simple, and Fedora is not simple. The Fedora command can only be illustrated in the same way. Linux has different versions. What is my GodaddyServer installed?
Recently, in order t
to throw it? There are two ideas, one is to modify php.ini, and the other to change the Web. config.Modify PHP.ini:
Modify the php.ini file as follows
Log_errors = Off
In addition, PHP closed warning error, modify the php.ini file error_reporting, by default should be:
Display_errors = Offerror_reporting = E_all ~e_notice
If modified to this or appear warning error warning also removed:
error_reporting = e_all ~e_notice | E_warning
Finally restart IIS

The first part of the site to build the two main elements: domain name and server, this time to say is the domain name resolution, that is, the domain name and server binding process.When we visit the network, the URL is sent to DNSServer, which is then returned by DNSServer to the ServerIP address that we are going to ask for an interview. As stated in the previous article, there may be multiple sites or subwebs on the same IP address of a server, at which point the data we request is received
International Domain name Registration agency ICANN has on October 15 in the global increase in international domain name wholesale prices, the wholesale price of COM domain name rose from 6 U.S. dollars to 6.42 U.S. dollars, net domain name wholesale prices from 3.5 U.S. dollars to 3.85 U.S. dollars. This is the first increase in the price of a registry since 1999 when ICANN established a price system for the two top-level domain domains.
Today, login to each domain name registration site, fou
