To create a vector in C++, you first have to include the vector library.
You do this by adding the line #include \x26lt;vector\x26gt; at the top of your file.
This line goes after the line #include \x26lt;iostream\x26gt; and any other header files you've included in your program.
The std::vector is included in the #include \x26lt;vector\x26gt; library..
Initializing a Vector in C++
The vector in C++ stores the reference of the objects and not the data directly.
These objects can be of any data type like integer, char, string, etc.
Unlike static containers like an array, a vector does not need a size to be initialized with..
There are two ways to vectorize a loop computation in a C/C++ program.
Programmers can use intrinsics inside the C/C++ source code to tell compilers to generate specific SIMD instructions so as to vectorize the loop computation.
Or, compilers may be setup to vectorize the loop computation automatically..
Vectors are a modern programming concept, which, unfortunately, aren't built into the standard C library.
They are found in C++, which is an object oriented programming extension of C.
Essentially, vectors replace arrays in C++..
The C++ Standard Library vector class is a class template for sequence containers.
A vector stores elements of a given type in a linear arrangement, and allows fast random access to any element.
A vector is the preferred container for a sequence when random-access performance is at a premium..

Underneath the hood a vector is an array which automatically resizes itself once the array is filled.
Once the capacity is reached, there is a pause in your program while the elements are copied over into a new array with a larger capacity..
Vectors are the dynamic arrays that are used to store data.It is different from arrays which store sequential data and are static in nature, Vectors provide more flexibility to the program.
Vectors can adjust their size automatically when an element is inserted or deleted from it..
A vector, in programming, is a type of array that is one dimensional.
Vectors are a logical element in programming languages that are used for storing a sequence of data elements of the same basic type..
Vectors in C++ are sequence containers representing arrays that can change their size during runtime.
They use contiguous storage locations for their elements just as efficiently as in arrays, which means that their elements can also be accessed using offsets on regular pointers to its elements..
Vectors are not ordered in C++.
Vector elements are placed in adjacent storage and can be easily accessed and traversed across using iterators.
In vectors, data is inserted at the end when we use push_back() function ..
You cannot use std::vector without including that file, because the compiler then doesn't know a class called std::vector .
The compiler only knows the language C++, not its standard library.
In vector, each element only requires the space for itself only.
In list, each element requires extra space for the node which holds the element, including pointers to the next and previous elements in the list.
Insertion at the end requires constant time but insertion elsewhere is costly..
