vintage vector

Author: wogoyixikexie @ gliet In the past, I had been wondering how this "arm exception, disruption, and their vector table" was, and how they actually implemented it, I did not expect to see the arm system developer's Guide: Design and optimizing system software chapter about arm exceptions, interruptions, and their vector table. -- ARM Embedded System Development: the original English version of software

By November Rain Date: 8:41:19 The vector class provides the function of increasing arrays. As more elements are added to the array, the array becomes larger. After deleting some elements, the array becomes smaller. Vector has three constructors, Public vector (INT initialcapacity, int capacityincrement)Public vector

In C ++, the string length can be obtained through string. Length (), which is not so easy for an array. For example, an array of int type: Int A [] = {1, 2, 3, 5, 6, 9}; how to obtain it? By using the special usage of sizeof, we all know that sizeof () is the size of the space occupied, so we can: int length = sizeof (a)/sizeof (INT ); to obtain the number of elements in array. 1. Storage and output of Vector Data: # Include # Include # Include Usin

Function Function prototypes Description constructor function Vector (); Create an empty vector Vector (int nSize); Create a vector with the number of elements nsize Vector (int nsize,const t t); Creates

Example of vector in C ++ I. Overview Vector is part of the C ++ standard template library. It is a versatile template class and function library that can operate on multiple data structures and algorithms. Vector is a container that can store various types of objects. Simply put, vector is a dynamic array that can sto

In many places the SVM is very obscure, not easy to understand, recently saw a good blog post well written, coupled with their own understanding, re-comb the points of knowledgehttp://blog.csdn.net/zouxy09/article/details/17291543First, the introductionSVM is a classifier. We know that the purpose of classification is to learn a classification function or a classification model (or a classifier) that maps data items in a database to one of a given category, which can be used to predict unknown c

1.vector iterators Incompatible Find the code that raised the error as follows:for (Vectortype::iterator it = Somevector.begin ();; it!= somevector.end (); ++it;){if (*it== value){Somevector.erase (IT);}}Code, after the erase operation, the loop continues without modifying it, and the assertion appears when compared to end ().The main problem here is that vector can implement erase in any way, not guarantee

1. Vector (continuous space storage, you can use the [] operator to quickly access random elements, quickly insert elements at the end, but in the middle of the sequence of insertion, delete elements slow, and if the initial allocation of space is not enough, there is a redistribution of larger space, and then copy the performance cost . 2. Deque (continuous of small pieces, the small pieces are connected by a linked list, and in fact there is a poin

Erase operation Problem of STL vector One boss said csdn on the blog ("Erase operation on STL vectors", address is: http://blog.csdn.net/tingya/archive/2007/12/28/1998442.aspx) Black Strange, Holding the mentality of curiosity, I also go to gather ha lively, found a little problem, report to everyone. The author says the following code is wrong: vector M_uintvector.push_back (10); M_uintvector.push_ba

 "Lanmanck Original" This article has already said STM32 's start-up process: http://blog.csdn.net/lanmanck/article/details/8252560 We also know how to jump to the main function, then, after the interruption, then how to run to interrupt the entry address. As you can see from stm32f10x.s, a whole bunch of interrupt response functions have been defined, which is the interrupt vector table, designator __vectors, which represents the interrupt

1.0 Vector Overview:Vector vectors container, I have seen a lot of the definition of vector names, for example, indefinite long arrays, vectors, variable groups and so on. In fact, these are called according to the unique nature of the vector.It can not only be like an array of elements to random access, but also the end of the insertion of elements, is an efficient, simple container, completely to a certai

STL learning: STL library vector, string, set, map usage, stlvectorCommon Methods Vector 1. Random Access, element insertion at the end; 2. Automatic Memory Management; 3. header file # include 1. Create a vector objectOne-dimensional:(1) vector (2) vector (3)

String, vector, stringvector 1. String object1. string s;S. size (); // Returns the number of characters in s, which is also the length of s; // The string object does not end with a NULL Character // Size () returns the string: size_type, that is, the unsigned type, instead of the int type.2. Add two string objects The "+" operator is overloaded in the string standard library; String s1 ("holo "); String s2 ("world "); String s3 = s1 + s2; // O

1. Vector point Multiplication The result of dot multiplication between vector A and vector B is a scalar defined as a. B = A1 * B1 +... + an * bn. 2. Vector LengthThe length of vector V is also a scalar, defined as | v | = SQRT (V1 * V1 + V2 * V2 +... + VN * VN ). Visible V

This example shows the vector usage in C + + and shares it for everyone's reference. Specifically as follows: I. Overview Vector is part of the C + + Standard Template Library, a versatile template class and function library that can manipulate a variety of data structures and algorithms. Vector is a container that can hold various types of objects, simply put,

introduction of vector diagramRecently, I learned about the concept of vector graph (vectordrawable) when I was "slimming" in the Android App.Starting with Android5.0 (API level 21), there are two classes that support vector diagrams: vectordrawable and Animatedvectordrawable. Vectordrawable is a vector graph that defi
