the "simple" solution in post 5 (after unfucking it so it would compile) still truncates everything after a space.

edit:

never mind, i forgot the thread spanned two pages and my statement is redundant.

To specifically answer post #29: You didn't read my previous post. One can pass a C++ string into a C-string situation by passing ElStringo.c_str (). The c_str () method represents the string as a C string. It is readable, not writable.

Of course!

Now..., how do I get that 'string' function to work?

The <STRING.H> is recognized, but it says 'string' is undefined symbol.

Ahhh, bit by schlock, after all. <string.h> and <string> aren't equivalents.

Ah... Right, right... So..., which header should I use in order to access the 'string' symbol?

By your own statement, it's a good guess it isn't that one. Let me be upfront here. There's a lot of help to be had. Insisting upon your right to be wrong is perfectly legal, but is probably not conducive to efficiently achieving your goal of finding straightforward solutions. I tend to rub a lot of people the wrong way. I don't lose sleep over it. I also don't tend to contribute (my time) gainfully in threads where the OP is refusing to consider the responses. I tried here, I failed. Ce la vie, or however one says it in non-redneck.

Oh, man... :p You are rich - I tell ya... You, are, priceless.
Awkward enough, my friend recites that latter comment quite a bit... *is now suspicious*

Anyway, seriously, now. Which header do I use to enable the 'string' function?

There isn't a string function. There is, however, a string class in the standard library of standard C++. Your problem is that the compiler you are using predates the standard. Such compilers sometimes had there own string class, but since there was no standardization of it, each complier vendor did it their own way.

I believe old Borland compilers (I have BC++ 3.1 somewhere) used the header file <string.h> and the class was called String (note the capital), but I might be wrong. Of course, even if I'm right, I don't know what methods the old version of the class supports.

You really should try to convince your teacher/IT staff/whoever that it's safe and worthwhile. Let them know that it's possible to obtain software that is free, legal, and safe, and that this will benefit any students learning to program. Let them virus-scan the installation files if this will make them feel better. It's my opinion that any computer lab used for teaching programming should have suitable tools available, and if they don't, the students should lobby for such tools.

Failing that, I believe resorting to subterfuge is appropriate. Bring in disks without being seen, or burn a CD and tell them it's music that you'd like to listen to while you work on your assignments after school (having music as well as the compiler would make sense).

Right..., right... I get it now. That blows...

Well, There's no header in Turbo C++ 3.1 which can "enable" or "provide" you string function (or class ...or whatever you want to say it...)

Although there are some way you have in Turbo C++ to input a full string.
The simplest you'd find is:

(Toggle Plain Text)

char *str;
str = new char; // for avoiding comipler runtime errors
cin >> str;

But it'll ignore everything after the whitespace(after you hit spacebar while entering a string).
To overcome this problem, try any of the below listed suggestions:

Through getline():

(Toggle Plain Text)

cin.getline(str);
cin.getline ( str, sizeof(str), '\n');

Through get():

(Toggle Plain Text)

cin.get( str, sizeof(str) );
cin.get( str, sizeof(str), '\n' );

Through read():

(Toggle Plain Text)

cin.read( str, sizeof(str) );
