Creating a Two-Dimensional Array

Explore how to create and work with two-dimensional arrays in C++. Learn the syntax for declaring arrays with rows and columns, initializing values, and understanding memory usage. This lesson helps you handle matrix-like data structures effectively in your C++ programs.

Two-dimensional arrays

A two-dimensional array is an array of arrays.

Two-dimensional arrays represent a matrix. We can access the element in a two-dimensional array by the row and column index. Both the row and column index start at 0.

Declaration

The general syntax for declaring a two-dimensional array is:

In the 2D array declaration, we specify the data type of an array followed by an array name, which is further followed by the row index and column index in square ...
