program runs so quickly I can't even see it

[Nobody/Anonymous]

HEllo there!
I'm a total newbie to C++ programing. After taking the very first lesson (creating the famous "hello world!" message on the screen), the executable runs so fast that I can't even see the command line window before it dissappears. I've already read the FAQ No.2 that says:
"2. When executing my dos program, it closes automatically. How I can change this ?

You can use an input function at the end of you source, like the following example :

include <stdlib.h>

int main()
{
system(PAUSE);
return 0;
}
"
but the result is exactly the same as before?! IS there a sloution to this?
P.S. I'm using Windows XP Pro

Hi Wayne!

I am using Dev-C++ 4.9.9.0 on a Windows XP Pro machine. Here's my code and the content of my compiler log:

include<iostream>

include<stdlib.h> //only needed if you are using Dev 4 family

using namespace std; //where the names are - like cout!

int main(void)
{
cout << "This is what that putz Wayne said to do!\n";
system("pause"); //keep the window open if running from Dev
return 0;
}

Please help!!!

Try this: Tools > Compiler > Settings. From there, set everything to No (blank for machine/processor settings).

It is best not to play with those settings unless/until you know what they are supposed to do....

Thanks, Jim!

It's working properly now, although I must admit that I still don't know why!

Probably not something you need to worry too much about at this point, but there should be a section on Compiler Options in Dev's Help. You can see for yourself how changes show up in the compile log....

Why it does not work might be the following compile option:

-nostdlib

Which explicitly turns off the C++ standard library stuff, which you are using.

I does appear that this thread was hijacked, I don't think the question that was answered was the one originally posted.

Post your full compile log, I suspect you are compiling a windows executable rather than a console one.

In case there could be be any confusion, make that:

Tools > Compiler Options > Settings
