3-D Vector

1. Standard Initialization of a 3D vector

A 3D vector is a type of vector having 3 Dimensions means a vector storing a 2-D vector inside it, similar to a 2-D array.

There are a few methods to initialize a 3D vector these are:

  1. Standard Initialization of a 3D vector
  2. Initialization of a 3D vector with given dimensions.
  3. Initialization of a 3D vector with some value

How to Initialize 3D Vector in C++ STL?

Prerequisite: Vector in C++

Vectors in C++ are the same as arrays with dynamic sizes having the ability to resize themselves, we can insert and remove elements from the end.
