 * 4) Add another watch using &age for the name. This will display

 * 6) Step Into the code for the function GetAge.

 * 7) The execution continues to the function header for GetAge.

 * 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.

 * 11) Verify the value entered is stored properly in age.

 * 12) Step into until the flow returns to main.

 * 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.

 * 16) Run to Breakpoint 1.

 * 17) Step over the function call to GetAge.

 * 18) Verify that the value entered was returned and stored

 *     correctly from GetAge.

 * 19) Stop debugging.

 * 5) Why is age greyed out in your watch window?

+ *

+ *  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.
