Beginning c++ Through Game Programming - Stuck with pointer errors!

dalel1035 (4)
Hello,

I am fairly new to c++ and am currently working through the book above. I am stuck on Chr 7 Ex 2 "Rewrite the final project from Chapter 5, the Mad Lib game, so that no
string objects are passed to the function that tells the story. Instead, the
function should accept pointers to string objects."

A previous question on this was raised in http://www.cplusplus.com/forum/general/53882/
but my problems seem to be different. I feel like I've searched the errors I get (35 in total, I will list them if requested), but can't find where I'm going wrong.

Many thanks in advance!

Your program just compiles and works. So what is the issue?

It must be something wrong I'm doing in visual studio then?

i get the following:

Update:

FIXED!
I switched the #include"pch.h" to the top (ie swapped lines 4 and 6) and it worked fine!

Not sure why really, I guess I'll have to look into what that line actually does. For now I've kind of been told to just type it and not worry about it.

"pch.h" is most likely the precompiled header. There is usually no need for it. You should be able to remove it at all and switch off using it in the project settings of visual studio.

If you use it it has to be the first include.

Thank you very much.
