Basic C++ programming tutorial

I'm a self taught programmer, I need to put a program together to teach students for free. Tasks 1: 1. Create a loop that executes 100 times, for each iteration it should print “Hi” followed by the current loop counter value. The loop should print "Low" to the output when the loop counter is exactly divisible by three. When the loop counter is zero, the output should just be "Hi" 2. Further modify the loop so that another, different message, is output when the loop counter is a prime number. Task 2: 1. Using an abstract class, represent a Shape, including a function for calculating the Shape’s area. 2. Use inheritance to create classes which represent four different types of shape, creating an instance of each. 3. Extend the program to read shape parameters from the user. 4. Add a feature of your choosing to demonstrate your additional knowledge. 5. Draw the shapes to an image file.
