Fairly Dumb C++ Question.

[AustinYQM]

Sorry to make this my first post.

I've been reading all over the internet about arrays and I just can't seem to find exactly what I need. All I want is to store strings into an array.

The hope is that I can make an array with strings like infile1.txt, infile2.txt ect ect.

Then use the fstream to open a file based on a varible. So if array[32] = infile32.txt then somewhere down the line I could have a function that would be called something like filetoopen(string).

So I'd have a while loop. that called the filetoopen() function using a varible like string helpfulVariable ; That would cycle through the array.

Is this making any sense?

While looking all the internet I couldn't find how to make an array of strings. Not an array of characters that happen to be words like C. ACTUAL strings. Can anyone point me in the correct direction?

[lduguay]

CString array[32] = {"infile1.txt","infile2.txt....};

Replace ... by actual string, or better, use a loop to construct the filename.

CString array[32];

for (int i=0; i < 32; i++)
array[i].FormatMessage((_T("infile%1!d!.txt"),i);

See http://msdn.microsoft.com/en-us/libr...43(VS.60).aspx

Thanks I knew it was something simple. Can't actually use the loop cause its gonna but stuff like torch.txt and wall.txt but it made a simple example. Thank you again.

Edit:

Ok, I have a follow up question. How do I reference it? Assume that I want the array called locationArray. I want to use a new line for each entry of the array for readiability and ability to change it later on. Would this work?

CString locationArray[4]
locationArray[0] = "example0.txt" ;
locationArray[1] = "example1.txt" ;
locationArray[2] = "example2.txt" ;
locationArray[3] = "example3.txt" ;

would that be correct? assuming so would I then do.

string storeVariable = locationArray[2] ;
cout << storeVariable ;

Thanks again for any help. I am very new to arrays.

Is there a specific reason you are mixing and matching std::string and CString?
One is standard C++, the other is a Microsoft-specific class.

More importantly, where is your book? Something is way wrong if you feel the need to be asking these trivial of questions on a forum. I recommend Accelerated C++ by Koenig and Moo - it is a great book for a beginner to C++.

This being C++, you almost certainly don't want to be using raw arrays. The idiomatic C++ method is to use containers like vectors and lists. You can find references for using them all over the place, I like using this one.

That said, I agree with Zhivago. You probably want to find yourself a basic C++ intro that would explain all of this to you.
