First we distinguish the next few confusing keywords:
New (also known as new operator), operator new, placement new. Look at the following code:
The new here is the first of the three keywords
1. Native operator new
Let's start with native operator new. Consider the following code, which is used to allocate five int-type spaces and return the pointer to them [1]:
Int* V =Static_castInt*> (::OperatorNew(5 *Sizeof(* V )));
For the above call, operator new plays the native memory allocation role, similar to malloc. The above is equivalent:
Int* V =Static_
A new (new operator) and operator new Object Dynamic creation method: New T; The essence is a two-stage operation: 1 uses operator new for memory allocation: void* operator new (size_t size). 2 invokes the corresponding constructo

Recently in a base project to do the demand, in the base code to see a large number of overloaded operator New/delete of the wheel code, and this is not too much to pay attention to, so take the time to carefully check the data, wrote the demo code, and finally th
opportunities, I have done a lot of other different types of projects, access to a variety of programming languages. In recent years, I've been getting all the attention back to Java, and I'm surprised to find that many programmers are talking about almost exactly the same thing that I did when I first started Java more than 10 years ago. You know, the industry we live in claims to be a fast-moving one. In fact, this more than 10 years, in the field of development has been a lot of
This article describes the differences and linkages between the three types of new/delete.New operatorThe new operator (new operator) is an operator commonly used in our C + +, such as a * a = new A; Create a pointer to a object.The new operator is divided into two steps:1.
"Placement new "? What exactly is it? I also heard about it in recent days. It seems that I am still far away from C ++! Placement new is a standard and global version of operator new. It cannot be replaced by a custom version (unlike ordinary OperatorNew and operator Delete can be replaced with the user-defined version ).
Its prototype is as follows:Void * opera
Recently, a problem has been encountered, others use the VS tool to create a new project, do not know how, there is no way to create a new filter.Today, finally solved, recorded, also hope to help more people.When there are more and more files in our engineering catalogue, we need to set up a smart selector for file classification. In fact, the project built with the VS tool has a brush selector by default.

I have changed three companies over the past few years. I often encounter a temporary addition to a project team for development. It is especially important to improve my work efficiency while understanding the business, because the project is always in the "catch up" status.
