nascar cin

Well, the subject is related to Chinese processing, so it requires C + + to read Chinese characters for processing.First use the wchar_t character, which is the wide character, and then define:1#include 2#include 3 4 using namespacestd;5 6 intMain () {7wchar_t*ch;8scanf"%s", ch);9printf"%s", ch);Ten return 0; One}View CodeAnd what's the result? No output 、、、So we changed:1#include 2#include 3 4 using namespacestd;5 6 intMain () {7 wchar_t ch;8CH =Getwchar ();9printf"%c", ch);Ten return 0

In the competition, when big data is encountered, the reading file becomes the bottleneck of the program running speed, and it needs a faster reading method. It is believed that almost all C + + learners have stumbled on the slow speed of the CIN machine, and since then vowed not to read data from CIN. Others say that the speed of Pascal's read statement is less than scanf in C/s and C + + players can only

The main application of Java in ACM is the big data class [personal opinion ]. Make a summary and use it as a template. The default class name is main. Input: Declare an input object CIN; CIN = new expect (system. In ); Enter an int value: int A = cin. nextint (); Enter a large number: bigdecimal A = cin. nextbigdecima

calculates the first expression and then the second expression. The value of the comma expression is the value of the second part. (4) The comma expression is the expression with the lowest priority. 5. strcmp () -- compares two strings. Two string addresses A and B are accepted as parameters. If AB is the same, 0 is returned. If A is prior to B, negative numbers are returned. Otherwise, positive numbers are returned. (The String constant enclosed in quotation marks is its address .) 6. clock

AlsoYou can expand on an empty vector object, or you can extend the vector of an existing element.The following code is a container that adds 2,7,9 three elements from the tail to the V, so that the three elements in the V container are 2,7,9 because the tail is added.Code://Cin,cout Need# include//Vectot Need# include//The accumulate algorithm requires# includeusing namespacestd;intMainvoid) {vectorint>v; V.push_back (2); V.push_back (7); V.push_bac

The purpose of the Getline function is to read a line of characters from the input stream, similar to the Get function with 3 parameters.

JAVA input and output summary Standard input: Cin = new partition (System. in); cin. nextLine ();: enter a line, which may contain spaces. The function is similar to gets (); cin in C. next ();: enter a word, ending with a blank character, similar to scanf ("% s", str); cin. nextInt ();: Enter the integer data

"S" indicates two characters: 's' and '\ 0 '; 2.
