 The next function defaults to the order from small to large, and the pre function defaults to the order of the largest to the smallest;{3,1,2} results from Next are {3,1,2} and {3,2,1};The result obtained with the pre is {3,1,2},{2,3,1},{2,1,3},{1,3,2,},{1,2,3};The principle is as follows:The principle and use of "STL" next_permutation1, Encounter Next_permutation (permutation: The meaning of the sequence)Today, a simple question (srm531-division T

As we all know, the STL container class is for the object to store management. Although there is no clear limit to the inclusion of pointers in the STL container class, the STL does not care about the objects or pointers that you store in the container. But carefully consider the original intention of STL, the use of p

C + + STL common traversal algorithmDesign concept of STL's container algorithm iterator1) STL container through class template technology, to achieve the separation of data type and container model2) STL's iterator technology realizes the unified method of traversing container, and provides the basis for the unification of STL algorithm.3)

Stack stacks container The stack is a linear table, and insertions and deletions are made only at one end of the table. This end is called the top of the stack, and the other end is the stack bottom (stack Bottom). The element insertion of the stack is called the stack, and the deletion of the element is called the stack. Because the element's stack and stack are always on top of the stack, the stack is a LIFO table, the LIFO table.The C + + STL stack

STL provides six major components that can be combined 1, container (containers): a variety of data structures, such as vertor,list,deque,set,map. From the perspective of implementation, the STL container is a class template 2, Algorithm (algorithms): various algorithms such as Sort,search,copy,earse. STL algorithm is a function template. 3, iterator (iterator

iteratorsIterators provide access to objects in a container, and define the scope of the objects in the container. An iterator is like a pointer. In fact, C + + pointers are also an iterator. However, iterators are not just pointers, so you can't think they must have address values. An array index, for example, can also be thought of as an iterator.Iterators have a variety of different ways to create them. The program may create an iterator as a variable. An

The first task is to draw STL data OpenGL, which can be rotated, scaled, picked up (after picking, display the title number, node number), move the vertex position to change the shape of the object; the first stage: read and show how to read STL files generated by Solidworks model in STL: ASCII format of STL Files The

The result value is an integer.The following tab

STL function object STL not only enables us to write complex code more easily and quickly, but also makes the written code both standard and highly optimized. STD: vector //... STD: Sort (names. Begin (), names. End ()); Another elegance of STL is that it is highly configurable. In the above Code, the string element in the vector is sorted using the ClassState

Re-review the STLWhat is STL?STL (template and Standard Template Library), which implements type-independent algorithms and data types, requires that the type in the implementation be parameterized, allowing the user to make different types according to its needs.one or one-like introductionSTL, the standard Template Library, is a highly efficient C + + library with industrial strength. It is housed in the

STL Introduction (Standard Template Library) basic components of STL: Containers (Container), iterators (iterator), function objects (functions object) algorithm (algorithms) Iterators is a bridge between the algorithm and the container that uses iterators as parameters to access the container rather than the container directly as the parameter of the algorithm, using the function object as a parameter of t

Finally, I found the complete Chinese version of objective STL and gave it to everyone.The author explains how to combine STL components to maximize the benefits of library design. This information allows you to develop simple and direct solutions for simple and direct problems, and helps you design elegant methods for more complex problems. I described common STL
