The Internet has already solved the mouse exclusive problemArticleFor example, ogre + cegui + OIS perfectly solves the non-exclusive use of the mouse, and there is also an article on this basis to solve the no pointer problem of the mouse in the

In C ++, dynamic memory allocation is a double-edged sword. On the one hand, direct access to memory addresses improves the performance of applications and the flexibility of using memory. On the other hand, problems such as wild pointer, repeated

Chapter 6 pointer This chapter clearly highlights the sensitivity of beginners. I will also be unfamiliar with this part after a period of time without using C. Well, it is actually unfamiliar with the high-level pointer. Of course, there are

Plain old data structure, abbreviated as POD, is a type of data structure defined in the C ++ language standard. pods are suitable for systems that require explicit underlying data operations. Pods are usually used at the boundaries of the system,

Recently, I read the memory layout of objects with virtual inheritance levels in the inside C ++, and found that the implementations in different compilers are different. Therefore, I explored it myself. The result is as follows:First, let's talk

Boost: scoped_ptrAlthough it is easy to use, its ability to share ownership is greatly limitedBoost: shared_ptrThis limitation can be solved. As the name implies, boost: shared_ptr is a smart pointer that can share ownership. First, let's look at

Hash table is a promotion of ordinary arrays, because it can directly address the array, so you canO (1)To access any element of the array. To illustrate the advantages and necessity of hash, we first introduce the introduction of direct addressing

In a twinkling of an eye 《. the Net Discovery series has been released for one year. This article is the 10-13 article in this series. net platform knowledge to make a small summary and mechanism analysis, and introduce and focus on the impact of

C language implementation polymorphism, C language Polymorphism In the previous article "function pointers in the C language struct", we introduced the application of function pointers in the struct. This article starts further research. Purpose of

2. COCOS2D-X Memory Management MechanismIn C ++, dynamic memory allocation is a double-edged sword. On the one hand, direct access to memory addresses improves the performance of applications and the flexibility of using memory. On the other hand,

Memory Management in cocos2d-x Architecture Garbage collection mechanism: The so-called "garbage" refers to the memory space that has been used before and is no longer used or has no pointer. The mechanism for collecting and reusing these "spam" is

Heard someone say that there is no pointer in C #, so want to write a C # in the use of pointers;C # Pointers are unsafe code, that is, the pointer runs under unmanaged code.And there is a certain difference in the definition of pointers in C # and

For "program = data structure + algorithm" has been repeated to explain and think a lot of times, it seems to have some understanding, binary tree is a data structure, the implementation of the tour is the details of the algorithm, which add up is

Tag: Copy copy on write when string is writtenProgramme IIClass string{private:char* _str; static int count;};Set a static shaping variable to calculate the number of pointers to a piece of memory, minus 1 for each destructor, until it equals 0

because of its flexibility and high efficiency, C + + has always been one of the mainstream programming languages, but the allocation and release of its memory is managed by the programmer itself, which causes a memory leak when the program fails to

1, there are two cases: a pointer to a const object, const on the left side of *, cannot modify the point of the content. const pointer, const on the right side of *, cannot modify pointer pointing.2, when assigned to the pointer, you can narrow the

I. Introduction to memory Management1. Why should I have memory management?Mobile device memory is extremely limited, and each app can occupy a limited amount of memory.The following behavior will consume memory. Create an OC Object. Define a
