2. Two-Dimensional Arrays A two-dimensional array is an array of one-dimensional arrays. For example, int arr_20[2] [5] is an array with 2 elements which are themselves integer arrays of size 5. It is common to refer to the size of a 2-D array using rows and columns. In this example, arr_2D has 2 rows and 5 columns, and each row is an array of 5 integers. The following program allows the user to enter a 2D matrix (basically a 2D array of integers) and display it. Compile and run the following program to understand what it does. #include using namespace std; int main() { const int ROW_SIZE=2; /umber of rows const int COLUMN_SIZE=5; /umber of columns int matrix[ROW_SIZE] [COLUMN_SIZE); 1/2D array for (int i=0; i>matrix[i][h]:// read matrix elements cout
