Thanks for that clarification.

Hi Paul,

Could you explain the difference between using "extern" on a function verses a global function?

Say I create two files named Globals.h and Globals.cpp.

I code a function in...

Scratch this question. I found that VS "Express" 2012 is free. I was probably looking at the non Express version before.

Answers for the other questions still needed though.

Thanks,

The "Windows 8 compatibility assistant" says that Visual C++ 2010 Express installed in my Vista laptop is not compatible with Windows 8 Pro. However, I've learned that many programs that Win8's...

AH HA MOMENT!

I can see now that when the vector of structs is instantiated, space for the string is not allocated "within" the struct. Just a pointer to the string is the actual member in the...

This is what I'm trying to understand. How is the sizeof(MyStruct) the same for every struct when there is a variable length string in the struct? Without a variable length member in the struct...

Totally right. Being new to C++, I used the parenthesis for "myVect(8)" in my actual test code but used the [] in my example here. Thanks for catching that.



My understanding is that a vector...

A new question regarding vectors and iterators.

I declared a struct that contains integers and one string. Then I instantiated a vector to hold the structs and set the total number of structs. ...

I wrote a test program and yes, pre-increment doesn't skip the first element. Goggling shows that a for loop works like a while loop with the increment occurring at the end of the loop. Also...

Understand. Going back to your previous post, why is pre-increment faster than post-increment? And won't pre-increment skip the first element in the for loop?

Thanks,

Actually no, I'm not preferring method-3 because of less typing. Method-2 uses "vector<int>::size_type" in place of Method-3's "unsigned" which is not that much more typing.


Method 2:
for...

I put my question in that form to simplify what I was trying to ask. My basic question was whether Method-3 should always work under the conditions I set. Just trying to understand how vector...

C++ beginner learning how to use vectors.

I see that there are 3 ways to iterate through a vector.



Method 1:
for(vector<int>::iterator it = myVect.begin(); it != myVect.end(); it++)
...

My bad Paul. In hindsight I can see why you think my plan is to code most everything using globals and not using classes. The code I posted was just extending your example to verify whether my...

Would that be moving the enum statement before the struct statement?


Since I need to access the betInfoMap[4] in my "GetBets", "PayBets" and on every iteration of the crap table drawing routine...

Is this the correct way to use Paul's code of the map of structs in an array for 4 players?



#include "stdafx.h"
#include <string>
#include <iostream>
#include <map>

using namespace std;

Thanks for clearing that up Paul. Learned a lot from this thread. I did plan to only use your method in the future since it's easier to type but now I know it also works better.

Thanks,
Raptor

Guess I need to do more research since I really don't understand why the code I showed works different from Pauls. Thanks for pointing that out.

For other beginning C++ learners, here's a substitute for Paul's struct code. Tested and it works identically.



// The following code is equivalent to Paul's struct code and it works...

Yes, I did realize that but failed to say that "structs are like classes except they are always public by default". Thanks for clarifying it just in case I didn't realize it.



Yes, once one...

Hi Paul,

Thank you very much for taking the time to explain your code. Who would have guessed that even structs can have constructors. C++ books and web tutorials are so simplistic that they...

OK, am more than willing to buy another C++ book. Please tell me the name of a book that explains what Paul did with his constructor statement within a struct. None of my 6 or 7 C++ books nor hours...

Hi Paul,

Going over your code, that's an extremely clever method of setting up the structure so it can be initialized in the format you show in main. I Googled for over 2 hours and could never...

That is really helpful Paul. I'll try to figure out how to use that for 4 players. Maybe an array to hold the maps.

Thanks!
