 * 8) Step into one more time.
 * 9) Why did the address of age and value change?
+ *
+ * The address of age and its value changed because we entered a function, where it initialized
+ * a new variable with the same name, and gave it a different value. It is not overwriting the
+ * original age variable, it is instead creating a new variable.
+ *
 * 10) Step over the cout and cin statements.

 * 13) Step over one more time.
 * 14) Why didn't the value entered get transferred back to main?
+ *
+ * The value entered didn't get transferred back to main because we are not
+ * storing the return value of GetAge() to the variable age.

 * 15) Stop debugging and fix the error.

+ *  I believe age is greyed out in my watch window because we are not using the variable age to
+ *  calculate the amount of days. It is now using the newly initialized variable in the parameter of
+ *  CalcDays() which is "int years". So instead of age, I have years in my watch window.
