 * 9) Why did the address of age and value change?
+* Inside the function of GetAge, the int age is reestablished after already
+* being established at the start of the code to equal 0.However this time
+* age was defined to a specific number, so a default placeholder number was
+* asigned to age, which changes the stored value shown in the address.

 * 13) Step over one more time.
 * 14) Why didn't the value entered get transferred back to main?
+* The value entered wasn't reasigned to the age in main, it was just established
+* in the age in GetAge, by adding age = before the GetAge function, it assigns
+* the age in main to the age returned from the GetAge function.
 * 15) Stop debugging and fix the error.
 * 16) Run to Breakpoint 1.

 * 5) Why is age greyed out in your watch window?
+* Age is greyed out in my watch window because the function, even though it
+* calls for age, is expecting a years int. So by changing years to age,
+* it removes the grey and calculates properly.

 * 5) Age is 7300? Not even Ralph is that old.
 * 6) Why did the values for both variables change?
+* The values changed because then the function is called in main, it gives
+* age and days in that order, but when the function recieves them, it
+* expects them to be in order of days and then age. To fix this you can
+* either swap the sent values or the expected values. For my fix, I
