Help with Strings -- Please read
Okay, I have a problem. I have a string which contains the following.
'none$none$south.dat$none'
How would I seperate that string ($ being the seperator) into four seperate strings?
I learn by example, so please jot me down some code =) I'm sure it's not too hard, however I am not too familiar with C++ strings, as I am an ex-VB coder.
Better yet, email me with a reply.

not sure if this is a good way to do what you want, but it should work for any string with a few modificationsCode:int x, y, strcount, length; char yourstring[25] = "none$none$south.dat$none"; char *seperated[4]; y = 0; strcount = 0; length = 0; for(x = 0; yourstring[x] ; x++) { if (yourstring[x] == '$') { seperated[strcount] = new char[length+1]; for(y = 0; y < length ; y++) seperated[strcount][y] = yourstring[x-length+y]; seperated[strcount][y] = '\0'; strcount++; length = 0; } else length++; } for(y = 0; y < length ; y++) seperated[strcount][y] = yourstring[x-length+y]; seperated[strcount][y] = '\0';

You might also want to try the getline function if working with a input file "infile.getline(variable,4,'$')" this will read "none" into variable for 4 spaces and stop at the $ sign. You could also make the 4 a 5 or 6 and it would still stop at the $ sign. but allow for a bigger string. Try checking out ignore() to help aid the get line and maybe check the string.h lib for some ideas? Hope this helps

It is a file input. However, the key is that the $ may appear after any number of characters, so I need a function to stop at $, not at 4 or 5 or any characters for that matter, get what I mean?
Oh well, thanks for the code and the replies!
Best of luck to you all,

using getline() similar to this:
const int largestNumberOfCharacersExpected = //whatever;
char bufferName[largestNumberOfCharactersExpected];
ifstream.fin("myFile.txt");
fin.getline(bufferName, largestNumberOfCharactersExpected, '$');
will allow you to read characters into bufferName until one of the following happens:
a) the largestNumberOfCharacters expected - 1 number of characters have been read in
b) a $ char has been encountered
c) end of file character has been encountered
Okay, that would work, but I need exitString[51] to be able to be split into exitNorth[12], exitSouth[12], exitEast[12], and exitWest[12].
How could I do that with getline? That seems like the most logical idea...
Thanks,

couldn't you just use strtok() ?
