As a result, we are wasting time by tracking code.should be replaced with constants:1 Const Double 1.653;This may also reduce the volu

pointers inherited from A, B, and C pointing to the D virtual function table at the same time, therefore, the size of the D object is 28. If you change the declaration of d to class d: virtual public B, and virtual public C, the size of D will change to 32. In this case, the distribution of D in the memory is roughly as follows: Figure 3: Layout of virtual inheritance in memory (Case 1) The second case (the case in VC is also what Scott Meyers, auth

data structure. When memory allocation requests arrive, A specific algorithm is used to define a required part of the large memory for the user. After the user completes using the algorithm, it is classified as idle memory. This memory optimization method converts memory allocation and release into simple data processing, greatly reducing the time required for memory application and release. References 1.

. If it is not enough, order a C ++ standard from the C ++ Standards Committee. Do not read (including my books) from Chinese mainland ). Do not read any books about VC ++ or specific compilers. If you need to complete C language courses, you can buy a very small K R of the C programming language. Other books will not look at it. Do not learn C first, but C ++ directly. You didn't learn ancient Chinese first and then vernacular, right? Therefore, believe me, it is easier to make it easier. The

placement Delete, however, there is a gap between the idea and the landlord. This function directly releases the memory and no longer analyzes the structure. It seems that this Delete cannot be called outside through the delete keyword, this is generally called for the system when a placement new error occurs. As long as placement new is used, the analysis structure is generally manual. 4 floor pengzhixi: C ++ does not have the built-in "placement new" because it cannot provide a general purp

down and find fault.If you use const instead:Const double aspectratio = 1.653; Because the non-# define name should also have a corresponding specification changeAt this point, the constant name will enter the symbol table, so if the compilation error, the error message back to AspectratioMore than that, for floating-point constants, the use of const constants may result in a smaller number of codes than # define , because the preprocessor "blindly" replaces the macro name Aspect_ratio with 1.6

Smart pointers have a very powerful ability, and careful and judicious choice can bring great benefits. I do not deny the ability of smart pointers, although I have previously denied auto_ptr. Perhaps because of my own ability limitations, not realize the benefits of auto_ptr, but this possibility I feel is not big. But Auto_ptr is the simplest smart pointer, there are a lot of works around it, including Boost, Loki, Ace and so on, but unfortunately there is no one I can say I am familiar with,

macro name Ratio Replace with 1.653 "may result in multiple copies of the target code 1.653, which is not the case if you use a constant instead.When you replace a # define with a constant, there are two special cases worth saying:The first is to define a constant pointer (constant pointers). Since the constant definition is usually placed in the header file (so that it is included in a different source code), it is necessary to declare the pointer as Const. For example, to define a constant ch
