Practical Practice 1:
Creating Variables and using cout and cin!  

It is common practice to read in values and then verify them with
output. Getting into the habit of accompanying a cin with both a
prompt and a verification can turn out to solve many debugging
headaches in the future. At this point, this is also you may know how
to do in a C++ program as well and thus it is the focus on today's
worksheet. Remember, compile often. Every couple of lines. Don't try
to write 30 lines of code before compiling! Test in pieces!

1) Create a new project and new cpp file in your environment. You
should be getting very familiar with this process after several
attempts. If this is your first attempt, you'll find you struggle with
this step. By next practical this will be completely assumed.

2) Create variables of the appropriate type for the following
attributes of a student:
  - name
  - age
  - height in inches (or cm)
  - weight in pounds (or kg)
  - shoe size
  - employment status (part-time, full-time or none)
  - number of courses taken
  - number of credit hours taken
  - current GPA

First Item Example:
   string name;

3) Prompt, read in and test!
   A) Make a prompt for each variable.  Ex: "How old are you? ";
   B) Read in the variable from the console
   C) Output the value with some other text. Ex: "You are 12 years old."

First Item Example:
   cout << "What is your name? "; //notice the space before the " and no endl
   cin >> name;
   cout << "Welcome " << name << endl;

4) After each prompt read in and test, compile and debug. When
satisfied that your code is working correctly, go back and add a
prompt, read in and test for the next variable.

5) When you're done with all variables, try moving the "test" output
statements all to the bottom of the code. How does this change the
look and output of your code? When complete, you should have a program
that can read in lots of variables and can verify was read in.

Preparing for the final project!

In the final project here are some variables that will be required:

 -craft name   	     	    ex: Challenger
 -total mass		    ex: 1995806.42
 -fuel mass  		    ex: 1671487.88
 -ISP     	    	    ex: 180.3
 -gravity a constant value at 9.80665
