C++ programming

[swappo]

Hello,

I want to get started in C++ programming. I am running Ubuntu 7.10 and first need a compiler. I tried downloading g++ from synaptics package manager but when I check for its installation under Add/Remove Applications It is not listed. I don't need a tutorial on how to program in C++ since I have and older copy of a book. What I need is advice on how to download and setup the compiler and run a hello world program I created in gedit. Can someone tell me how to download the compiler and run main.cpp (my hello world program) from the tutorial directory in my home directory? I have searched google for over an hour with no luck. Thanks. BTW, here is the program I will run:

#include<iostream>

using namespace std;

int main(){
cout << "hello world!\n";
return 0;
}

If you've searched Google for beginning C++ programming with GCC and haven't found anything, you're obviously not using the right search terms. At any rate, here's what you'll need to get started.

Open up a terminal. Type this:

sudo apt-get update <enter>
Password: <enter your password>

Assuming you have an internet connection, you will see lots of messages about updates and whatnot. Then when you get your prompt back, type this:

sudo apt-get install build-essential

That will get you a working Gcc/G++ enivronment. Now to compile your code from the command line do this:

g++ nameofyourfile.cpp

Assuming you don't have any errors, that will generate a program called a.out. You can run it by typing this:

./a.out

If you want to name our output program something else, use this:

g++ nameofyourfile.cpp -o nameofyourexecutable

Replace "nameofyourfile" and "nameofyourexecutable" with whatever applies to you.

Thanks techieMoe, those were the exact instructions I was looking for. BTW, I was able to find alot of stuff on google, just not what I was looking for. I am still very new to linux but working to overcome that.
