One application needs to display stars corresponding to 11

One application needs to display stars corresponding to 11 random numbers and on the left side of the list, there need to be in intervals of 20 (starting at 0) all the way to 200, and on the left it needs to display the stars (which represent the random numbers generated) . The other program needs to store 20 numbers that are random from 0-100 and then print all 20 and calculate the average and the max value. I am really having difficulties implementing the random with arrays (which both of these require).
