7.3: Vectors in 2D

A 2D vector in C++ is a dynamically resizable matrix-like structure where each element is a vector, allowing for various operations such as ... Declaration and Initialization · Basic Operations on 2D Vector · Insert Elements

2-Dimensional Vector, also known as a vector of vectors, is a vector with an adjustable number of rows where each is a vector.

Also referred to as vector of vectors, 2D vectors in C++ form the basis of creating matrices, tables, or any other structures, dynamically.

Recall that vectors are comprised of two components: the horizontal component is the x direction, and the vertical component is the y direction.

If you know the (maximum) number of rows and columns beforehand, you can use resize() to initialize a vector of vectors and then modify (and access) elements ...

Use the std::vector::vector(count, value) constructor that accepts an initial size and a default value: std::vector<std::vector<int> > fog( ...

Vectors can also be represented algebraically, using component notation. The components tell us the extent of the vector along the coordinate directions. For ...

Vectors can be either two dimensional, with components in the x and y directions, or three dimensional, with components in the x, y, and z directions. Both ...

A vector describes a movement from one point to another. 2D vectors are added from nose to tail giving a new line from the starting point to the final point..
