Template enhancement 1. External template 1) Problems of traditional C + + In traditional C + +, templates are instantiated by the compiler only when used. In other words, as long as the fully defined template is encountered in the code compiled in each compilation unit (file), it will be instantiated. This results in an increase in compi ...

1, C + + multithreading 1.1 thread creation Create other threads by creating objects of the STD:: thread class. Each STD:: thread object can be associated with a thread. #include <stdio.h> #include <stdlib.h> #include <assert.h> #include <thread> #include <iostream> int k = 0; void fun(void) { //Thread sle ...

1, Experimental purpose (1) Learn to use VC to write basic Win32 console application (console application). (2) By creating processes, observing the programming and debugging operations of running processes and terminating processes, we can further get familiar with the process concept of the operating system and understand the "life" ...

First, let's look back: The code is as follows: class Solution { public: vector<string> permutation(string s) { vector<string> ans; string str; sort(s.begin(),s.end()); vector<int> visit(s.size(),0); permutationCore(ans,str,s,0,visit); return ans; } void permutat ...

A basic concept of queue container Concept: queue is a first in first out (FIFO) data structure. The queue container allows elements to be inserted from one end and removed from the other end. explain: Usually, the head of the queue is to remove data, and the tail of the queue is to insert data;There is no iterator operation in the queue, ...

1. Introduction to C + + operator overloading The operands of predefined operators in C + + can only be basic data types. But in fact, similar operations are required for many user-defined types (such as classes). At this time, we must redefine these operators in C + + and give new functions to the existing operators, so that they can be used ...
