Could someone please give me a link to a good totorial on c++ under linux, and maybe on how to use the gcc? i'm using gcc 3.2.3.

C++ in linux is the same as in Windows
g++ filename.cpp

xavier · Mar 3rd, 2005, 12:19 AM

In c++ i only worked in Borlanc c++ 3.1 ... and it might be simple but right now I can't get the hello world program going.

And yes, g++ filename.cpp ... had crossed my mind.

So, ... any links would be helpfull 10x

then it creates a fiole a.out and run
./a.out

Isn't most Linux programming done in C? I have a book at home called 'Linux Programming by Example' and everything is in C

Ok, when i try using "cout" it sais : `cout' undeclared (first use this function)

(Toggle Plain Text)

#include <stdio.h>
using namespace std;
int main(){
	printf("Hello");
	int c=2;
	printf("%d",c+1);
	printf("\n");
	cout<<"World"<<endl;
}

Again ... if u have any links with tutorial for c++

If you want to use cout, you have to #include <iostream> as well. I don't know why you're using a namespace that doesn't even exist in the header files you've included.

neither do I! that's y i was insisting on a LINK .... but no matter .. thanks for the help u gave me .. I'll take it from here

--------
Please correct me if there is any flaw in the steps.
Forgive me if I did not understand your question correctly and did not answer your question right, I am pretty new to Linux.
------------------------------
I'm assuming you have C++/C compiler and Vim editor already installed on your system.
In my opinion, Vim is one of the best editor for all purposes especially when I'm working with c++/c code.
Basically you can compile and run most of your C++/C programs from the editor.
First, learn how to use vim by typing -> "vimtutor" from your terminal. You might want to read every directions carefully in the vimtutor. After you get down the basics(or during its process), open Vim editor by typing -> "vim (yourfilename).cpp" from your terminal.
[following process takes place in the Vim editor] If you want your C++/C code to be neatly indented, type -> ":set cindent", and then start coding.
To compile the file, type -> ":make (filename)", if there is a bug, fix it. Okay, now you're done with compiling. To execute the program that you have written, type -> ":!~/(filename)". The program will be executed then.
