/*
 DOCUMENTATION

 Program Purpose:
 	Demonstrate proper format for documentation, test plans and comments.
 	Also demonstrate user prompts, keyboard input, simple calculations and output.

 Compile (assuming Cygwin is running): g++ -o GoodDocs GoodDocs.cpp
 Execution (assuming Cygwin is running): ./GoodDocs.exe

 Notes: in Cygwin, main must return type int

 Classes: none

 Variables:
 	name - char array sized for 131 characters - used to store user's name (one word only)
 	age - int - used to store user's age as an integer number
*/

/*
 TEST PLAN

 Normal case:
 	>What is your name? Richard
 	>What is your age? 21
 	>Hello! My name is Richard, and I am 21 years old!
 	>In 10 years, I will be 31 years old!

 Bad Data case 1 (more than one name)
 	>What is your name? Richard Huntrods
 	>What is your age? 21
 	>Hello! My name is Richard, and I am 21 years old!
 	>In 10 years, I will be 31 years old!

 Bad Data case 2 (nonsense or non-alpha name)
 	>What is your name? zb23xx!
 	>What is your age? 21
 	>Hello! My name is zb23xx!, and I am 21 years old!
 	>In 10 years, I will be 31 years old!

 Bad Data case 3 (negative age)
 	>What is your name? Richard
 	>What is your age? -1
 	>Hello! My name is Richard, and I am -1 years old!
 	>In 10 years, I will be 9 years old!

 Bad Data case 4 (floating point age)
 	>What is your name? Richard
 	>What is your age? 12.5
 	>Hello! My name is Richard, and I am 12 years old!
 	>In 10 years, I will be 22 years old!

 Discussion:
 	The program accepts only a single word for the name input (whitespace delimits the word - comma, space, period, etc.)
 	The program also attempts to convert the age input into an integer, even if this produces a nonsense result (i.e. 'five').
 	Negative numbers are allowed and processed as if legitimate, and floating point numbers are truncated.
