1. Variables/constants: what are the key differences between a variable and a 
   constant in C++?

A variable can be declared, initialized, and reset at different stages. A
constant can only be declared and initialized together, and can never be reset.
Constants should be reserved for values that will not change during the life of
the program, like TAX_RATE in Lab 2.

2. Variables/constants: name two things you found confusing in Ch. 0.

I didn't understand the description of printf or how it differs from cout. I
also don't understand the purpose of pseudo code.


3. Output: write well formatted C++ code to display the following text: 
   "Hi, my name is X and I'm Y years old.", where X is a placeholder for your 
   name and Y is a placeholder for your age. You want to use well-named 
   variables for both place holders.

string name = "Hank";
int age = "29";

cout << "Hi, my name is " << name << " and I'm " << age << " years old." <<endl;
