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

jquery Mapael is a jquery plugin based on raphael.js that can display dynamic vector maps. For example, using Mapael can show a world map that countries can click. In addition, you can mark cities with circles, squares, or pictures, with their longitude and latitude.

Summarize my experience and lessons in the work.
You can use the list, set, or map traversal to remove certain elements:
Correct use of Method 1
Copy Code code as follows:
std::liststd::listfor (itlist = List.begin (); itlist!= list.end ();)
{
if (Willdelete (*itlist))
{
Itlist = List.erase (itlist);
}
Else
itlist++;
}
correct use of Method 2
Copy Code code as follows:
std::liststd::listfor (itl
Sequential containers::(vectors and lists and deque)The erase iterator not only invalidates all iterators that point to the deleted element, but also invalidates all iterators after the deleted element, so erase (iter++) cannot be used, but the return value of erase is the next valid iterator, so the correct method is:: For (iter = C.begin (); ITER! = C.end ();)iter = C.erase (ITER);Associative containers::(map and set are more commonly used) The eras
