Populate a two-dimensional array with the following prices in this table order: 32.34 22.33 68.30 36.99 43.94 63.67 55.89 67.44 13.77 87.13 54.99 87.78 18.42 21.60 45.98 66.03 41.38 74.48 24.21 67.10 61.23 Write a method/function which uses loops and is called from main() that increases the prices by 6.5% and stores the new price in the same array. All changes to the array must be made inside the method/function. Please display the original array in table form as well as the new array with the 6.5% price increase.
