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

automatically adds '\ 0' to the last character '; Char a [] = "I am a student"; // The number of characters automatically calculated by the System [Remember] Do not forget to end an empty string when determining the shortest array required by the string. "S" indicates two characters: 's' and '\ 0 '; 2. String input: getline () for line-oriented input () Char a [20]; // it must be a char-type character arrayCin. getline (a, 20); // read the characters entered by the user into an array of 20 elem

To be compatible with the input and output of C, C + + uses the tie to flow input and output through the line bindings, so Cin/cout is not independent. The cout is also executed when CIN is executed. Vice versa.By Defalut,cin are tied to Cout,and wcin are tied to wcout.By default, CIN and cout are bound together, and w

Choose Sort, bubble sort, quick sort, merge sort, insert sort, hill sort, count sort, bucket sort, cardinal sortThese are some of the most commonly used sorting algorithms.Select sortfor (int i = 0; i int minval = A[i];int minid = i;for (int j = i+1; J if (A[j] MiniD = j;Minval = A[j];}}Swap (A[i], A[minid]);}The simplest is to choose the sort, that is, each time the array is traversed, then the first small, the second small, know that the entire array is ascending and orderly. So the complexity

It makes definitions made in the std namespace available to a program. cout Orcout int cheeses; cheeses = 32; cin >> cheeses; cout 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.

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
