so i have an item class that work with an inventory class, and i have created an item. If i were to check the item before adding it to the inventory it would show the name as potion and the count as 15. after i add it though it shows the count as 0 and i cant seem to figure out why.

changed compiler and problem went away. Found the issue to be due to included file by the ide

First I recommend that you stop using the C-strings and start using std::string. You can not use assignment with C-strings, you will need to use strcpy() from the cstring header. Second in your item class you have a pointer variable that you never allocate any memory ( char* ItemName;). How many characters will this variable be able to hold?

You should check to see what level your errors/warnings are at because your compiler should be giving you warnings about the "deprecated use" of plain char*. You should be able to increase the level or warnings/errors and you should always try to get rid of any warnings there might be.

taking in account your suggestion and adjusting the code to fit the std::string, i still receive a count of zero, when adding the item. even though the char* was deprecated it was always return the proper name. although i still changed it. what my issue lies in is that i am giving the inventory 15 of the same item, and then when i check it there are 0

I think it's time to take your "crazy learning" into the realm of debugging. On what OS and with what IDE are you developing?

[jimblumberg]

Show your current code, along with any warning/error messages exactly as they appear in your development environment.

Code is updated in first post and the the only error i get is from debug mode, not the compiler of segmentation access error and it points to the Item class getItemCount() method

Please don't change the code in you previous posts, it causes the responses to your questions seem incorrect. This will seem confusing anyone reading this topic. Always post your modified code in as a new post in the topic.

You have an error message, post it. If you get a segmentation fault run the program through your debugger it should show you the line where the error is detected.

I can do that from now on, but the error was exactly what i posted:

segmentation access error and it points to the Item class getItemCount() method

which is accessed from the inventory class during the getInventoryItemCount method

im using Windows 7 x64 and Dev-C++

[jimblumberg]

And what is the line where the problem was detected? The debugger will show you the actual line. Since this is not a complete program there is no real way I can tell why you are getting a segmentation fault. So you need to show the exact error message along with providing the exact line the error was detected. Otherwise post a complete program and maybe I can help.

Dev-C++ 

Ugh...there are so many better options available than an old, buggy, unsupported IDE like Dev-C++. Especially when you need to debug. Try Visual C++ Express, or Code::Blocks, or the more up-to-date version of Dev-C++, wxDev-C++.
