The difference of map::erase function in different versions of STL 1. c++98 and C++11 standardshttp://www.cplusplus.com/reference/map/map/erase/ 2.PJ STL (Windows) map::erase function (C++11 standard) returns a map::iterator: iterator Map::erase(const_iterator _where); iterator Map::

The function of the erase is to invalidate the iterator as a parameter and return the iterator that points to the next parameter of the iterator.As follows: Copy Code code as follows: List Particlesystem; List::iterator pointer; if (Pointer->dead = = True) { pointer = particlesystem.erase (pointer); } There is a program about using erase incorrectly. Copy Code code as

For the following code: 　　 my_container.erase(iter); My_container is a container of STL, and ITER is an iterator pointing to an element in the container. If it is not in the for, while loop, There is no problem in deleting elements in this way. If you are performing m_container iteration in for and while, deleting all elements that meet the conditions may cause problems. If m_iner iner is iterated in for and while, deleting all elements that meet the conditions may cause proble

Today, we found that some STL: map code runs well in windows, but it cannot be compiled in Linux: "no match for 'operator = 'in' iter = ". It is actually a simple line of code: Iter = map. Erase (ITER) The description of MAP: erase on msdn is as follows: Iterator erase (iterator it );Iterator erase (iterator firs

Original: HTML5 Erase effect for eraser　　Disclaimer: This article is original article, if need reprint, please indicate source waxes, thank you!　　Recently the project just used this effect, that is, a bit like a scratch card, on the mobile device, a picture is scraped off to show another picture. As follows:Demo Please poke right:demo 　This is quite common on the Internet, originally wanted to directly online to find a demo to apply his method on the

clip method. The usage is simple:Ctx.save () Ctx.beginpath () Ctx.arc (X2,Y2,A,0,2*MATH.PI); Ctx.clip () Ctx.clearrect (0,0,canvas.width,canvas.height); Ctx.restore ();The above code realizes the erase of the circle area, that is, to implement a circular path, then use this path as the clipping region, then clear the pixels. One thing to note is that you need to save the drawing environment first, to reset the drawing environment after you have clear

First, IntroductionReview Javac The compilation process of the solution syntax sugar when you see the generic erase in the example, the information on the Internet is mostly more specific, in this make their own some detailed and understandable summary.Ii. Introduction of generic typeGenerics are a new feature of JDK 1.5, a paradigm used by compilers, a kind of syntax sugar that guarantees type safety. Note: In inheritance, the subclass generic number

Erase statement Reinitialize the elements of a fixed-size array and release the storage space for the dynamic array. Erase array The array parameter is the name of the array variable to clear. Description It is important to determine whether an array is a fixed-length array (regular) or a dynamic array, because Erase to perform different operations based on the t

Author: arm-WinCE In many forums on the internet, I have seen a question: how can applications directly read and write flash sectors, or a similar question. In short, it is hoped that the application can directly access the flash device, directly read and write data in the sector, or perform other operations. I tried to introduce my methods to you. First, let's give a brief introduction. Wince supports flash devices, generally nandflash or norflash. The FAL + FMD architecture is used. We imple

Files deleted on the computer, usually, if not specially handled, the system simply deletes the file name in the allocation table, and the real data is still on disk. With some data recovery software, it's easy to recover files that have been called deleted. The partition assistant has the ability to erase the disk, it can completely delete the data on the disk, so that the data on the disk can not be erased or deleted by other data recovery software

, then type-erase, and erase to object. The so-called type checking is at the boundary (where the object enters and leaves), checking to see if the type conforms to a certain constraint, and simply includes: The left and right side types of an assignment statement must be compatible. The actual participation of a function call must be compatible with its formal parameter type. The expressio
