These are only suggested practice exercises - they do not have to be turned in.

• Write a function to calculate the minimum, maximum, or average value of an array. The function should be passed the array and an integer representing the size of the array.
• Write the code to get an integer in the range 1-5 from the user. If the integer is outside of this range the code should print an error message and request a new number.
• Write code that uses nested loops to print a 10x10 multiplication table.
• Create a class called creature that represents creatures in an Artificial Life simulation. The data members of the class should include the x, y, and heading of the creature represented as integers; and the current energy of the creature represented by double. The heading stores a value from 0-3 representing up, down, left, right. Write a constructor that sets the x and y to random values in the range -1000 to 1000, the heading to a random value from 0-3, and the energy to 100. Wrtie a print function that prints the position, heading, and energy of a creature. Write a move function that decreases the energy by 0.1 and changes the position of the creature by 1 bases on it's heading.
• Write a swap() function that uses pass-by-reference to swap the values if two integer arguments.
• Write a swap() function that uses pointers to swap the values if two integer arguments.
• Using a node class create three nodes in main() and in main() change their next pointers so that they are linked together in a short linked list.
• Write a node function print() that prints a linked list from beginning to end. Modify the function to print the linked list in reverse order.
• For the exam you may want to practice going from decimal to binary to hexadecimal and vice versa.
