Programming C++

Below is the question.

Below is the starter code.

Below is the grading rubric for what is needed to receive full points.

I do not want another answer posted on this that was used for a previous question. Will give thumbs up for correct answer.

Loops Drawing a tree In this programming assignment, you'll draw a tree based on user specifications. The starter program draws a tree, using a triangle with three levels as the leaves and a rectangle with four levels as the trunk. 1. Modify the above program to ask the user to specify a number of tree trunk levels (Enter trunk height: "), then use a loop to draw that many levels. Testing suggestion: If the user specifies 4 tree trunk levels, than the original tree should be drawn. 2. Modify the program again to ask the user to specify a number of tree trunk "s per level ('Enter trunk width: "), then use a loop to draw that many "s per level. You'll need to use a nested loop in which the inner loop draws the "s, and the outer loop iterates a number of times equal to the number of tree trunk levels. 3. Modify the program to ask the user to specify a number of tree leaves levels (Enter leaves width: "), then use a nested loop to draw that many levels. You'll need two inner loops for drawing the leaves: one for outputting spaces and one for outputting .'s. The outer loop iterates a number of times equal to the number of tree leaves levels. Note: Your program only needs to support odd-numbered widths,like the below examples. Here is an example program execution (user input is highlighted here for clarity): Enter trunk height: 7 Enter trunk width: 3 Enter leaves width: 5
