Ok I am extremely new to C++ and I managed to get my hands on a copy of Visual Basic C++ (the latest version) for free. I created a new project as a "General" prject adn it is empty. Then I added a new item as a .cpp file. Then I entered basic code to display a message as:

Quote:
#include <iostream>
using namespace std;

int main ()
{
cout <<"This is my first C++ program.";
return 0;
}


I can't seem to find the run button to make it work. Should I be looking for a run button. Do I need to enter a command? I have no idea. Right now I compile it (shows it as 1 succeded) and run it by pressing on "Debug". When I do this, the Win32 window shows up, maybe for 1 second, and then quickly disappears. How can I run it or get it to show up constantly. Thanks for answering this extreme newb question. Very Happy

You need to add a pause before the return.

That's wrong. And zylum, you should know better Laughing

You need to run the application from the terminal window (command prompt).

Build the solution first, then run it without debugging from the debug menu.

That is what I am doing right now because I just figured out how to get input from the user.

What do you mean by command prompt? I am stupid. Very Happy

Tried building the solution and ran it without debugging from the debug menu but it still quits on me.

Thanks for your help and quick responses. But I still need help. Thanks guys. Smile

Ok so.... Use this to have it say "press any key to continue" system("PAUSE");
Here is the proper code:
#include <iostream>
using namespace std;

int main ()
{
cout <<"This is my first C++ program.";
cout<<endl; // This just drops it down a line to print words
system("PAUSE"); // This pauses the script until a key is pressed
return 0;
}

Awesome I will use that. Thanks. Right now I am just doing

int stop;
cin >>stop;
return 0;

Actually, I would not use that. What you have with the cin >> stop is better then system ("PAUSE"). system ("PAUSE") only works with windows, while cin >> stop is cross platform

Sure it's cross platform but it's cheating. You can't just call for a variable everytime you want to pause when a pause function exists...

In which case, cin.get() is also there. On another note using the command line is a better alternative

Alright, conclusion reached. If your cross platform developing, or dont want it to say "press any key to continue..." then cin.get() is a greate way to do it. Smile

Cool but I am a new person to C++ so I wouldn't worry too much about cross platform development. Smile What do you mean by using the command line?

You should.

The command prompt is the terminal window you get when you go to Start -> run -> cmd

I know what the command prompt is I don't know what he meant by "using the command line"

Post subject:  RE:Extreme newbie
he meant that using the command prompt is a preferred way to starting your program

code:

cd "C:/path/to/app folder"
./app_name.exe


Since this is the type of an application you are developing.

He meant run theprogram while inside of the command prompt.. example: run>>cmd>>cd desktop/ >> programname.exe

No I know how to run the program inside command prompt I just didn't know if he meant C++'s command line window at the bottom or command prompt. Also I tried running it through command prompt and it still closes but it doesn't close when I use system ("PAUSE") which means it is going on to return 0; and quiting. Therefore I guess it was a problem with my code. If you think not than please tell me what else is wrong. Smile

On a side note. Very good and useful forum here and the members seem to be very helpful. Very Happy

Also on another side note. Razz Do any computer classes after grade 10 teach C++? Is it school dependant? Do ALL schools teach Java?

What should happen is that you open the command prompt, run the application, have it print the output, finish, exit. The command prompt should remain open. If your application is closing the otherwise open terminal, you are doing something wrong.

On your unrelated note -- it is school dependent. Some schools don't teach upper year CS at all.
