June 8, 2018 today is the second day of learning R feel slow, need to speed up a bit. In addition yesterday seems to write not particularly good, so today intends to study the overall editor.Today to learn the factors, first: what is a factor? Because we know the vectors in R, and because we've been learning python for a while, we have an understanding of dictionaries, arrays, etc. So, for the factor I can be seen as a vector with a little dictionary

Before blogging about some of the uses of Std::find and std::find_ if, but not about the custom classes stored in vectors, how to use Std::find and std::find_if to find them. First define a class: Class Item { private: std::string m_itemid; int m_price; int m_count; Public: Item (std::string ID, int price, int count): m_itemid (ID), M_count (count), M_price (price) {} int GetCount () const {return M_count } std::string Getitemid () const {return

the container to be reserved. The resize function can have two parameters, the first parameter is the new container size, and the second parameter is to add new elements in the container. If this parameter is omitted, the default constructor of the element object is called. The following are examples of the two functions: ???? Vector Because the source code of the two interfaces is quite simplified, You can paste them here: ?? Void? Resize (size_

C++11 provides us with smart pointers, which brings us a lot of convenience.So what if the unique_ptr is the element of a vector container?form the same:vectorBut how do you add elements to VEC?See below:#include#include#include usingnamespacestd;int main(){ vectorint>> vec; vec.push_back(1);//错误 return0;}First define a unique_ptr and then Push_back ():#include#include#include usingnamespacestd;int main(){ vectorint>> vec; unique_ptrint

Use vector containers, that is, to avoid the search, so today we list some STL find algorithm applied to the vector. Find ()Returns an iterator to the "the" in the range [First,last] that compares equal to Val. If no such element is found, the function returns last. #include find_end () searches the range [first1,last1) for the "Last occurrence of" sequence defined by [ FIRST2,LAST2), and returns a i

Python implements the 12306 ticket snatching and automatic email sending reminder payment function, python12306 # In front of this article, I have already developed this program. However, the code of the entire program will not be posted because of the scalping and lazy people. This is purely a technical exchange. Only technical exchanges ,,,,, Well, after the program ends, you still have to pay manually. If you don't talk much about it, let's start

Near the spring Festival these days to buy the ticket peak, www.12306.cn as the only official website to buy train tickets, was flocked to the crowd to repair the miserable.

The effect of this tutorial is somewhat similar to the vector painting effect. The production method is also relatively unique, the early stage is basically to use filters and layer mixing and so on to make similar vector color block diagram. Later refinement processing, and finally in accordance with their favorite to polish it. Original 　　 　　 Final effect 　　 　　 1, open the original material,
