differences in scanf and CINAs you know, there are two types of inputs, outputs,-SCANF and CIN in C + +, but there are differences between them, you know. Let's take a look at the assessment below.
Test questions:Enter n number, output n number.
test Environment:
ubuntu12.04 i3cpu 4G memory 7200 RPM HDD
Test Code:(in order to test the correctness of the results, keep the other parts (except the input and output)
scanf's code:
#include
the
One: standard input function cinIt represents the standard input device-the keyboard, which belongs to the stream, and his usage is the same as that of the stream. That is, the:cin>> variable; Enter multiple variables that can be written on one line, such as:cin>>x>>y>>z; This is not good to read, generally in the front of the input statement, you have to do a hint, "Please enter XXX".In addition, this function does not have the address symbol "", also does not have to write the variable type, m
When learning C + +, these input functions get a little confused, here to do a summary, in order to review their own, but also hope to be able to help later, if there is a mistake in the place also ask you a lot of advice (this article all programs through the VC 6.0 run) 1. Cin2, Cin.get ()3, Cin.getline ()4, Getline ()5, gets ()6, GetChar () Attached: Cin.ignore (); Cin.get ()//skipping a character, such as the unwanted carriage return, space, and other characters 1,
#include
The above code loop completes the character input
Here is one of the output results:
Enter characters; Enter # to quit:
Ken Run#really Fast
Seekenrun
9 characters Read
Analysis: Why the program output ignored the space.
Explanation: The reason is in CIN. Spaces and line breaks are ignored when CIN reads. Therefore, the spaces in the input are not echoing, and the count is not included.
Ad
Do nine degrees, due to the large amount of data, in many cases, using scanf and printf in place of CIN and cout for input and output, or the error timeout can not AC.
There are three suggestions for increasing the input/output speed of C + +: At the the the the the the the the the the the the the I in main Function,add:std::ios_base::sync_with_stdio (false) which cancel Thesynchronization between

A = 'B'; B = 'O'; C = 'y ';
Putchar (a); putchar (B); putchar (c); putchar ('/N ');
Putchar (66); putchar (79); putchar (89); putchar (10); // 10 is the ASCII code for line feed.

C ++ Input and Output
Reposted in this article: blog.csdn.net/zhanghaotian2011/article/details/8868577blog
The input and output are not formal components in the C ++ language. C and C ++ do not provide a special statement structure for the input and output. defined, it is defined in the I/O library provided by the compilation system 。The output and input of C ++ are implemented in stream mode. Figure 3.2 and Figure 3.3 indicate the process of C ++ inputting and outputting through stream 。
