I know nothing about C++,i know Visual Basics, if that is any help here. Can anybody give me some pointers on where to start and possibly some tutorials? (i know there are some on this site, but if any of you know some other really good ones, it would be appreciated). Any help would be nice
.
the best things in life are simple.
I don't want to sound like an idiot but.... like I said, I am a n00b. What is a header file? What are their uses? How do I make one? I keep seeing isostream.h in the tutorials, but I get errors about the file not being found, is that file supposed to be on my comp already or do I have to make it? Any help on this would be greatly appreciated....
Visual Basic was so much simpler....
what compiler do you use??
Is it a C compiler or a C++ compiler?
C++ Compilers should already have the iostream.h file in the DIR\Includes directory,
if you have C++ compiler and its not showing, make sure u include it like this:
#include <iostream.h>
NOT
#include "iostream.h"
hope that helped
"There are three kinds of people in the world...
Those that can count and those that can't."
I use Microsoft Visual Studio 6.0 Enterprise Edition, which includes Microsoft Visual C++ 6.0
thats what i use, do i dont understand why the file isn't there if you said it should be.... Please i am lost here....Code:#include <isostream.h> int main () { cout << "Hello! This is my first C++ Program!"; return 0; }
That should be iostream, not isostream.
was the isostream a typo just here or is tht how you spelled it in your program. Its iostream
hahahaha, i feel like a dumbass. LOL. just a simple typo, oh well, i'll take this advantage to ask a few more questions. what are header files used for?
They provide functions and consants and the like for use in your program.
For example, math.h provides constants like Pi, and functions like square root and the trig functions.
how do you know which ones contain the functions? also, can you get more than what originally came with the compiler?
The bnest way is to open up the header files and take a look through them.
Tur13o,
Header files contain a collection of "library" files (functions).
For example, sqrt() is a library (.lib) function contained in the header file <cmath>.
When the compiler sees a preprocessor directive such as #include <cmath>, those files (functions) are added to your code.
(Yes, all of them!)
When you elect to access a particular pre-defined function, the compiler looks to see if the appropriate header file has been "included". If it has, you're "golden". If not, you score a compiler error.
That is, you've attempted to access a function that's not part of your code.
Not an elegant explanation, but I hope it helps.
