Write a simple, but complete C++ program that defines a 2D array to help manage the inventory of a local supermarket. Each row represents a commodity. Columns are defined by the figure below. In the table, left three columns are input, right four are output. Remember that the code should be as simple as possible.

Id	Price	Sale	Inventory	Sale-In Dollar

The main() function does the following.

1) Read the commodity (row) number from the keyboard with proper prompt.

2) Populate the left most four columns using random number generators.

3) Update the elements of the fourth column and calculate the elements of the fifth column, which should be the product of the second column element and the second column element at the same row.

4) Print out the content of the 2D array before and after the calculation in Step 3).

Note: To use the random number generator, add following code

#include

#include

srand(time(NULL));

var = rand() % scope; // scope is the range starting from 0
