Modify the previous assignment as follows:

Allow the user to input MULTIPLE DELIVERIES, for up to 5 deliveries but possibly fewer.

Keep the functions you wrote in the previous assignment.

FOR EACH DELIVERY: Store the number of sandwiches, total cost, and total profit in a two dimensional array (these values are the results of the functions). The array size should be 5x3, with each row representing a delivery of 1 or more sandwiches.

Finally, display all the details stored in the array in table format. Also display the average delivery cost and average delivery profit (call a function to calculate and return these values. The function takes the array, array size, and a call by reference parameter as arguments. It also returns a double through the return statement).

i started my assignment but it's not workinh like i want
for example if i order 1 sandwiches

the arrays output is 1   2   -1
                     1   2   -1
                     1   2   -1
                     1   2   -1
                     1   2   -1

                     if i order a second one the first order won't stay in memory
