Alternatives to arrays

Vector: Included in namespace Std

Vector<typename> name (N_elem);//Create a vector object named name, which can store n_elem elements of type TypeName

function is more powerful than arrays, but inefficient

Array

Array<typename, n_elem> name;//creates an array object named name that stores N_elem elements of type TypeName.

N_elem can not be variable, efficient and array-like, but more secure and convenient.

Array, Comparison of Array,vector

Each element can be accessed using standard array notation

Array objects can be assigned to another array object, and arrays must be assigned value by element;

Array objects and arrays are stored in the same memory area (stack), and vector objects are stored in free storage or heap;

Arrays tend to be hyper-bounded, unsafe to behave, array and vector objects can also be accessed out of bounds, but can be prevented by member functions at ();

When you use at (), illegal indexes are captured during run time, and the program is interrupted by default, and this extra check causes the runtime to grow longer.

There are also member functions, begin (), and end () to determine the bounds.
