Sequent container: (vector) Erase iterator not only invalidates all iterators pointing to the deleted element, but also invalidates all iterators after the deleted element, therefore, the erase (ITER ++) method cannot be used, but the erase return value is the next effective iterator. The correct method is ::For (iter = C. Begin (); iter! = C. End ();) Iter = C. Erase (ITER );Associated container: (MAP) the

Balance between vector, map, and list From: [http://www.codingnow.com/2004/board/view.php? Paster= 776] I want to create a data structure to store data in an orderly manner for convenient search, and the efficiency of data insertion is not too low. When the data is almost unchanged, vector is the best solution. We only need to put the data in. After sort

[i], index)); Strvec.push_back (index); Index + =1; }Else{Strvec.push_back (strm[str[i]); } }returnStrvec;}Here, a map is used to hold the key-value pairs for each character and index, and the index is represented by index, starting at 0.The final sequence of numbers is saved with vectors.Loops through the entire string, looking for a character in the map each time, if not found, adds it and t

box:For the choice of coordinate system, depends on your data, if it is a GPS device measurement points, you can directly select 4326, so that the map coordinates can be used directly. If you get coordinates from a network map such as a gold map, you select the appropriate projected coordinate system, or the feature location you create is incorrect.2. Field defi

Maps are associative, andvectors,lists,anddeque are sequential in type. Map: Underlying mechanism rb-tree(red-black tree), automatic ordering of elements, key-value pairs. Vector: operates in a similar way to array, with dynamic space growth. is a continuous space that supports random access. Advantages:? Memory is dynamically growing and does not require a specified memory size.? Support for random access

Question: uva11991easy problem from rujia Liu? (MAP + vector) Give you n numbers, which may be repeated. Then, in m queries, ask the subscript of the k V. If such a number does not exist, output 0. Solution: map each number and subscript for one-to-one ing, but because the same number appears multiple times, an array is required and the length is not certai

When vector loops are removed, erase (IT) returns the address of the next iterator, and the insurance practice is to assign it to the IT it= erase (IT) This is caused by the vector's internal mechanism, so pay special attention to whether the iterator will fail when the vector is erase! Map can be directly erase (it++); Neither

Take a look at the Remove2, comment out the Remove1, and delete the Remove2 annotation.Run error, vs2005 Expression:list iterator not incrementable, description list iterator ++iter problem.List is a two-way list, after erase (ITER), ITER expires, printf ("0x%x", ITER); The result is 0, and only the erase return value can point to the next element. the correct usage of REMOVE1 is: vec.erase (Remove (Vec.begin (), Vec.end (), 5), Vec.end ());the correct usage of Remove2 is:lst.remove

New Skill get!ProblemFor containers inside C + +, we can use iterator for easy traversal. But when we make changes through iterator to Vector/map and so on, we need to be careful, because operations often lead to iterator failure, and subsequent behavior becomes unpredictable. Like what:#include The description of std::vector::erase in Cplusplus's reference is:

Value is primarily used to store values and can also be used for conversion of valuesEx:value A = value ("123")Value B = value ("AA")Log ("a=%s,b=%d", a.asstring (). C_STR (), B.asint ());Vectors are primarily used to store specific data spaces for continuous subscript accessVectorA.pushback (Label1);Map is stored by key value (the key value can be any value)MapB.insert (1,a);Vector is a continuous
