al Arrays 2. T A two-dimensional For example, int arr 2D(31I4] is an array whose elements are themselves integer arrays of size 4 It is common to refer to the size of a 2-D array using rows and columns. array is an array of a one-dimensional array. in this example, arr.20 has 3 rows and 4 columns, and each row is an array of 4 integers The following program allows the user to enter a 20 matrix (basically a 2D array of integers) and display it. Compile and run the following program to underst tand what it does using namespace std; int main() const int ROM SIZE-35 //mumber of rows const int COLUN SIZE-4 IInumber of column int "atrix[NON SIZE][cou5TE); //20y for(int i 0,i,RON-SIZE i .. i) IZE-3 Iumber coutcc Enter data for rov"ci 1e and columtj+1 tin, 'matrix[i][j];// reod trix elment s for (int $- ROM S1ZE; i) Modify the provided program to compute the sum of the elements across rows and columns. You will have to declare two one-dimensional (1D) arrays named row sum and column sum, of appropriate size to store the respective sums Initialize al elements of these arrays with zerors Display sums of the rows and columns stored in row sum and column, sum along with a suitable message. No formatting is required to display the sums. Complete the requested changes, and then save the file as Lab6B. epp, making sure to compile and run the program to verify that it produces the correct results.
