In practice, the vector series in c ++ -- vector traversal (stl algorithm, vector iterator (do not judge not equal to end () in the loop), operator [])
There are many ways to traverse a vector container.
Index traversal:
for (i = 0; i
Iterator traversal:
for (vInt::const_iterator iter = v.begin(); iter != v.end();it
I've never used it before.vector#include #include intMain () {structSt {intA };STD:: vectorV V.resize (4); for(STD:: vector:: Size_type i =0; I operator[] (i). A = i +1;//v[i].a = i+1;} for(inti =0; I STD::coutSTD:: Endl; }}Compile successfully with VS2015, run result:1234However, this is only allowed after c++11, the compiler does not allow you to write such a syntax, the vector container is not allowed to
C ++ copies the content in a vector to the end of another vector and ends with the vector.
When using the vector container, We need to copy the content of a vector to the end of another vector. How can this problem be achieved?
Previous blogs about vectors you can use the Insert method to copy a vector to the back of another vector.Previous blogs have also talked about the need to transfer ownership if the vector container is placed inside the unique_ptr.Come on, now. 818 HowvectorIf you have a regular vector, we can use insert like this://inserting into a

What is container
Container, as its name implies, is a place for storing things. C ++ containers store certain data structures for data search or sorting or other special purposes. As we all know, common data structures are similar to arrays.Array, Linked listList, TreeTreeStackStack, QueueQueue, HashHash Table, SetSet, I

Vectors are collections of objects of the same type. Each object in the collection has a corresponding index. Vectors are often referred to as containers (container).To use vectors, you need to:
