 This is a summary of efficient C ++ programming, which is very helpful. I. # differences between # include "filename. h" and # include # Include "filename. h" indicates that the compiler will start searching for this file from the current working

Two classic categories of classesClass without pointer member (s)ComplexClass with pointer member (s)StringDefensive statements in the headerComplex.h#ifndef __complex__#define __complex__Code#endifInline Functionfunction is automatically a

Reference one side of the unknownJava does not support pointer, only provide Reference, beginners are often puzzled, especially the information structure of the students, their minds the first thought is: "No pointer, how this, it can not be done

4 design and statement • Software design, the steps and practices of "making the software do what you want it to do," usually begins with a fairly general idea and eventually evolves into full detail to allow the development of special interfaces

1. In the beginning, C + + was just C plus some object-oriented features, originally named "C with Classes" (C with Class).2. Today's C + + is already a multi-generic programming language, supporting process form (procedural), object-oriented

I. Differences between # I nclude "filename. H" and # I nclude # I nclude "filename. H" indicates that the compiler will start searching for this file from the current working directory. # I nclude indicates that the compiler will start

Design and declaration of Objective C ++ classes and functions In the course of reading Objective C ++, I have been sighing for countless times. This is a good fucking write. Therefore, I decided to write the content of this book into five blogs

recently the company recruit more, thus interviewed a lot ofC + +programmer. During the interview, I would ask questions about parameter passing, with particular emphasis on pointers. Because the pointer is after allC + +one of the most important

I. Resource managementResource management is our application of resources, whether it is memory, mutexes, files, etc., after use, all need to return to the system. C + + does not have its own garbage collection mechanism, so it is very important to

C + +is a language, just its grammar, characteristics, standard class library is already a very advanced curriculum, so in the beginning of learning, must first lay a good foundation. Know what to focus on when we're learning about it.One, #include "

Abstract: Technology lies in communication, communication, reproduced please specify the source and maintain the integrity of the work.A ReferenceReference: As mentioned before, his main function is to alias, similar to pointers, implementation is

6.1 Clause 18: Make interfaces easy to use correctly and hard to use incorrectly) Clause 13 indicates that the customer places the newly applied resources in the smart pointer to avoid resource leakage. A constructor provided by STD: tr1: shared_ptr

One of the C + + Knowledge Points series (go + organize)Do not forget to add a semicolon after the class declaration, otherwise there will be many errors!!One of the C seriesOne, #include "filename.h" and the difference between #include#include

introducing this chapter, we will explain the strategy of passing parameters to function functions in ECMAScript. In computer science, this strategy is generally called "Evaluation strategy" (Uncle Note: Some people say translation into the

Turn from: 18 Questions to be aware of to learn C + +One, # include "Filename.h" and #i nclude difference# include "filename.h" means the compiler will look for this file from the current working directory # # means the compiler will start looking

Don't be influenced by the idea of Java programming, the terminology in computer science- passed by reference (pass-by-reference). Do not make yourself a self-talk personal language.These terms are also not specific to Java, and you should not learn

vector Vec; 1. Simple lambda Auto it = std::find_if (Vec.begin (), Vec.end (), [] (int i) {return i > 50;});Class A {public:bool operator (int i) const {return i > 50;} }; Auto it = std::find_if (Vec.begin (), Vec.end (), A ()); 2. Lambda

18. Make the interface easy to use problem: Parameters of the interface Interface relies on other calls classDate {public: Date(intmonth,intdayintyear;}The above code problem: Easy to pass parameters in the wrong order

Before reading "Head first Java", remember that there are mentions, Java in the call method, passing parameters, the use of Pass-by-copy method, passing a copy of the content, that is, the value of the transfer.To give a simple example:1 Public
