Task 1:
Question 1: Declare a double array of size 100.
Question 2: Fill out the array with 1 if a random value is greater than 0.5 else 0
Question 3: print the number of 0's in the array .
Question 4: Explain the approach you follow to solve the problem. Include statements, data structure, critical points that you test to insure it works correctly.

Task 2:
Question 1: Declare a 2-D boolean array of size 5 and 10.
Question 2: Fill out the array with true if a random value is less than 0.5 else false

Question 3: Print only the indexes of cells with true value.
Question 4: Explain the approach you follow to solve the problem. Include statements, data structure, critical points that you test to insure it works correctly.

Task 3:
Question 1: Declare a 2-D boolean array of size 40 and 20.
Question 2: Fill out the array with blanks and *s to create a Christmas tree
Question 3: Print only the tree.
Question 4: Explain the approach you follow to solve the problem. Include statements, data structure, critical points that you test to insure it works correctly.

Task 4:
Question 1: Declare a 2-D integer array size 20 and 40.
Question 2: Fill out the array with random numbers less and equal to 6; and greater and equal to 1
Question 3: Print the max number of each row .
Question 4: Explain the approach you follow to solve the problem. Include statements, data structure, critical points that you test to insure it works correctly.

Task 5:
Case study: Assume you are given a code solution (a class) for a simulation that counts how many times an event happens. You are asked to run the simulation several times to estimate the average of time. Explain the approach you will follow to write the necessary code for the assigned task. Include statements; also, the data structure that may need to be reset to default values; critical points that you will test.
