10.

Write a small program that asks the user for two numbers and you need to display back the biggest number of the two numbers that he gives you. Ideally you would use modules. Remember that you always have the Control module, then we usually have three other modules, one which caters for the input, another for the calculation, and another for the output. Also remember that in pseudo code you use Print to output on the user's screen, and Enter to wait for input from the user's keyboard. Also remember to declare the variable data type before using a variable.
