02nd ACM/ICPC competition STL Introduction

1. STL STL (Standard Template Library) is an important part of the C ++ language standard. STL takes the form of template classes and template functionsProgramProvides various data structures andAlgorithmIf programmers can make full use of STLCodeSpace, execution time, and coding efficiency are greatly improved.

Principle of memory distributor in STL

Note: memory management is always the red-light area of the C/C ++ program. There are two focuses on memory management. One is the correct use of memory. For example, new and delete in C ++ should appear in pairs and use raiI to manage memory resources, auto_ptr and other aspects, many C/C ++ books use the introduction of skills. The other is the implementation of memory management, such as the slab distributor of the Linux kernel, Allocator implementation in

STL for common 3D file formats

I recently used 3D files in STL format to learn how to add them to my favorites. From: http://www.cnblogs.com/ourshell/archive/2010/05/03/1726821.html STL can only be used to indicate closed faces or bodies. STL files can be in either the plaintext format or binary format. Its file format is very simple Plaintext:Solid nameFacet normal Ni NJ NKOuter LoopVertex v1

Overview of STL Container C + + STL (Standard Template Library Standard Template gallery) is a universal class template and algorithm collection, it provides us with some standard data structure implementation such as queues (queue), lists (linked list), and stacks (stack) and so on. When we use C + + programming, we often use the STL container, which is very

Imitation functions in STL

Functors uses the function object name in the C ++ standard ). Imitation functions are mainly used in STL algorithms. Although function pointers can also be used as algorithm parameters, function pointers cannot meet STL's abstract requirements, and cannot meet the requirements of software blocks-function pointers cannot be used with other STL components, resulti

Differences between STL, ATL, and wtl

STL (standard template library STL) is a general term for a series of software developed by the HP lab. It was developed by Alexander Stepanov, Meng Lee, and David R musser while working at the HP lab. Although it mainly appears in C ++, this technology has existed for a long time before it was introduced into C ++. STL

Gdb debugger command learning summary notes STL printer

Http://blog.csdn.net/sunlylorn/article/details/6788768 GDB user-defined commands are very useful. You can use user-defined commands to directly operate the data in the container and conveniently view the data in the STL container. This link dbinit_stl_views is a custom command written by Dan C Marinescu to view STL containers (you can modify it if it is not suitable for your

Data Structure and underlying implementation of MAP and set in STL

Abstract: This article lists several basic STL map and STL set questions. By answering these questions, we explain the data structure in the STL associated container, finally, we raised the question about the built-in balanced binary tree library functions and map and set selection in Unix/Linux, and analyzed the advantages of MAP and set. For those who want to l

It is mainly suitable for beginners and has some reference value for understanding STL. The notes are illustrated in images and texts, I hope to help you better understand STL. Main threa

The six components of the STL--Allocator (memory allocation, what's so esoteric)

SGI designed a two-tier Configurator, the first-level configurator directly uses malloc () and free (), and the second-level Configurator uses different strategies depending on the situation: when the configuration chunk exceeds 128bytes, the first-level configurator is called when it is "large enough", and when the configuration area is less than 128bytes, As "too small", in order to reduce the additional burden, the use of complex memory pool collation, and no longer recourse to the first leve

STL source code analysis --- stl_hash_set. Read notes

STL only specifies the interface and complexity, and does not require specific implementation. The set is mostly implemented by the red/black tree, but STL provides a so-called hash_set in addition to the standard specification, which is implemented by hash table. Hash_set interfaces and hash_table are provided. Therefore, almost all hash_set operations directly call the hash_table function. In addition to

Efficient stl--non-standard hash container

STL is built on generalization. The array is generalized to a container, and the type of the contained object is parameterized. function generalization is an algorithm that parameterize the type of iterator used. Pointer generalization is an iterator that parameterize the type of object being pointed to. Six components in the STL: containers, Algorithms, iterators, Configurator, adapters, functor.These six
