Vectors are vector types that can hold many types of data, such as several integers, so they are called containers. Vector is an important member of the C + + STL, and you need to include the header file when you use it:

Vector is a set of objects of the same type. Each object has a corresponding integer index value. The standard library will be responsible for managing
In practice, the vector series in c ++ -- vector (unique_ptr () is assigned to vector (unique_ptr ())
Previously, we mentioned that the insert method can be used to copy a vector to the end of another vector.
