C++ Question

[Hags]

I did not see any other forums with c++ as a possible subject so I am taking it here. I am just starting to learn the programming language. Now I am sure anyone even a little experienced with C++ knows about the "Hello World" program that almost everyone writes as a first practice code. I am using Dev C++ as a compiler just in case this helps. Now whenever I write the hello world program, it compiles and runs fine but it only flashes on the screen for a very breif second. Now I know there is a line of code you can insert at the bottom of your project to make the dos prompt type window stay open so you can read your project but I forgot what it is. Does anybody know what the line of code to make the dos window stay open so I can see what I've done?

use "getchar()"
example:

include< cstdio >
include ...
.....
do whatever output line

....... then in the end:

getchar(); // equivalent to PAUSE in DOS

----------------------
the above line stop the program for as long as you wanted until you press a key on the keyboard.

I written batch programs before that output directly to the console and to do this I just wrote PAUSE. Hope it helps.

On a personal note I found it easier to start with managed code like C#. Here is a link to some great tutorial videos:

I just thought the managed code seemed similar, plus this is running on Microsoft .NET 2.0. I don't know if Dev C++ is the newest one.

Also you can get C# Visual Express for free and it allows you to develop MS SQL Server applications completly free of charge. It's pretty cool.

add the header: #include
add this line before your "return 0" : getch();

*edit: wait...sorry. dunno if this will work. i do C only. you can try it though*

[Hags]

cool, thanks guys, the getchar(); worked like a dream, I haven't tried pause yet but I wil, thanks again

Also, try loading the program from the command prompt. That'll keep the text up there. What OS are you using?

You could start up the command prompt (Win Key + R), type in cmd and then you can navigate folders in the command prompt to the folder with the executable in. Use cd _folder name_/_sub folder_ and ../ to navigate up (Like C:/Documents and Settings to C:/). Then type in the name of the executable once your in the project folder.

Hags , Blue60007:

I dont think, that will work with programs compiled using Windows-based compilers; it will work with DOS based compilers.
because a Windows-based compiler will create a executable which will open a "child window" when you run/executed it. therefore same thing happens....window open prints output, then closes window.

[blue60007]

You sure? I've never used Dev C++ so I don't know how that works.

I'm using VS .NET 2003 and I can run programs as I described just fine.
