A key part of this project is the use a two-dimensional array.
Because of the shortened timeframe, you are not writing this from scratch, you are taking a running programming and adding 3 “features”
Before getting into the changes, here is a description of the program.
The program uses a two-dimensional array of int to represent the number of daisies that are located in a spot. When the program starts, it will initialize the 2D array with random numbers.
There is a do-while loop that handles the interaction with the user. Inside the loop it will display the 2D array, get a command from the user, and then perform the action requested.
The “gather” is implemented. It asks the user for a row and column to indicate a spot and it reduces the value in the array by 80% to simulate the gathering of daisies.
The program keeps track of the total number of daisies gathered and when the user chooses to exit, the number of gatherings is displayed.
Three Changes
The three features are different and you could tackle them in any order. So, if one seems easier to write first, then tackle that one first.
The “M” command currently has no code. The idea here is that element with the greatest number of daisies is identified by displaying the row/col.If multiple locations have the same value, then indicating one of them is fine.
The gatheringMessage() method currently has no logic. The idea here is that a message will be returned based on the totalDaisiesGathered.

What? no daisies picked
1-499
That isn’t too many daisies
500-999
That’s an acceptable number of daisies!
1000-1999
Fantastic!
2000+
That’s getting to be too much!
The “G” command currently has no input validation and will crash if the row/col entered is out of range.Add a validation loop for row to make sure it is not = NUM_ROWSAdd a validation loop for col to make sure it is not = NUM_COLS
Note: An earlier draft of this project had ragged arrays but this project does not use ragged arrays
“M” Command (30 points)
gatheringMessage() method (30 points)
row/col validation loops (30 points)

Sample Snippets
A separate document will have an entire sample run. Here is just some portions of a run to illustrate the changes.
