1. Linear list: The data elements of a linear table are stored with arbitrary storage units (this set of storage units can be contiguous or discontinuous)#include using namespace std, #define Elemtype int#define Status int#define error-1#define OK

Application of 1 PairPair is the combination of 2 data into one data, when the need for such a requirement can be used pair, such as the map in the STL is to put key and value together to save. Another application is when a function needs to return 2

void Mainwindow::selectfile ()//Select file (GIF) {path = Qfiledialog::getopenfilename (This,tr ("Open File"), ".", tr ("Text     Files (*.gif)); Ui->lineedit->settext (path);}       void mainwindow::selectfile_2 ()//Select folder {path=qfiledialog::

Think of that day headline interview, let me hand kmeans, but a long time without C + +, a lot of forget = = faint sadnessThis time just to catch the chance, you can try again, I wrote the project, there are multiple filesFirst: Base.h#ifndef base_h#

1. Linear table (Linear_list):Characteristics:In a non-empty finite set of data elements There is only one data element known as the "first one"; There is only one data element known as the "last"; Except for the first one, each

The fill and Fill_n functions are part of the 12th generic algorithm for C + + primer and call them generation and mutation algorithms, meaning that these two functions can only operate on elements that already exist in the input range . Attempting

Binary Lookup in STLSupport originalThe functions of binary lookup in STL are three Lower_bound, Upper_bound, Binary_search. These three functions are used in an ordered interval (which is, of course, the premise of using a binary search).For

Array 1. Storage of arrays in memoryAn array is a collection of some kind of data that is stored continuously in memory, with no gaps between adjacent data.Some type: It can refer to the basic data type, road int type, float type, char type, double

What I want to share today is a write about the string, so let's start with the simplest. The main function defines a string variable, and we want to know the length of the string. The length of a string usually refers to the number of characters

I believe that for many people who have just come into contact with programming, there is a question in mind, what is an object-oriented, and why should we object-oriented.First, we look at the official explanation, object-oriented is a way to
