Welcome to my blog! Here I plan to post information on things I'm studying and working on.

Below are the review questions and my answers for lesson 3 of C++ In One Hour A Day.

1. What is the difference between a signed and an unsigned integer?
   • Signed integers can contain negative numbers. An unsigned integer of the same size can contain 100% more numbers but no negatives.
2. Why should you not use #define to declare a constant?
   • #define is an outdated method for declaring constants which replaces text with a value.
3. Why would you initialize a variable?
   • Initializing variables ensures their values aren't random.
4. What is the value of QUEEN from this line of code?: enum YOURCARDS{ACE,JACK,QUEEN,KING};
   • 2
5. What is wrong with this variable name?: int Integer = 0;
   • Nothing. It compiles without error.
