As you've probably guessed, I'm onto my very first "Hello World!" C++ program, which seems easy enough.

In Ubuntu, I've opened up the text editor and I've written the code and saved it as a .cpp which worked fine.

In the terminal, after taking it to the place where I saved my .cpp, I wrote:
g++ -Wall -W -Werror hello.cpp -o hello

It created a file in that folder, with no extension, which I guess is expected on Linux.

If I type "./hello" (without "s), it says Hello World! on my screen. Great.

Now the issue is that when I head over to the folder where hello is saved, double-clicking it won't do anything.
How can I change it in a way so that it won't need to be opened using the terminal, but rather simply by being double-clicked?

Thanks in advance, and I apologise for my noobiness. I guess we all start somewhere

 

From the top of my head: easiest way to do this in Ubuntu,

create a shell script (echo "./hello" > run.sh) , make it executable (chmod +x ./run.sh)
double click the run.sh file, and Nautilus will ask what to do with the shell script (run, display in terminal, edit, etc)

note: when doubleclicking the ./hello executable from Ubuntu, it does actually run the executable, but because there is no GUI, no output is shown, because its not run in console mode/terminal.

The best fix is to actually instantiate a gui-window (for example with GTK), and output the text there.. see http://developer.gno...#SEC-HELLOWORLD

 

I've actually encountered another issue! I didn't want to make a new thread, so I'll post it here:

So I've written my very first extremely basic code in a file called Functions2.cpp

This is what it consists of:

Code:

#include 
int Add (int first, int second)
{
std::cout 

 

Thanks man, I added the two lines

Code:

char response;
std::cin >> response;

Before the return 0; bit and it worked.

Not too shabby for my first day!

 

it means a pointer to a long.



edit:
long is a type that is the same as a long int: http://en.wikipedia.org/wiki/C_data_types
as the variable name says, it's an array of pointers to longs. the video should explain the pointer idea. and then it's just a list of those.
