My First C++ Program...

[Saint Nick]

I just want to know how I can set it so that it doesn't close the DOS window when I compile/execute it.

 

[xtknight]

A cin.get() with no parameters should do it.

 

[Saint Nick]

Well... it was working, now it isn't? I started writing a new program though.

Option 1:
Open a DOS window and run it from there, instead of double-clicking the exe.

Option 2:
add:
system("pause");
as the last line of main() before returning.

I think system("pause") only works on Windows.. so you might wanna take note in case you run it elsewhere.

Something irrelevant here.. but you can use using namespace std; instead of putting std:: on every line.

I actually just noticed cin.get() didn't work on the second call. No idea why...
What's the C++ equivalent of getch()? Anyone?

cin

Why does cin.get() not work on the second call? It wasn't halting the program for me as I remember, and apparently not for the OP either.

 

[drinkmorejava]

try doing a void main() and do not return 0;.

you could always loop it.

At the end, you could have:

while(1);

So that it loops forever.

or turn the whole thing into a loop and set up a condition at the end.

I think it's because it still keeps the first input.

while(1);

That semi colon will make it loop on that one statement, thereby doing nothing.

try doing a void main() and do not return 0;.

That won't help.

I usually just use getchar() anyway.

If you're using Visual Studio, there should be a "!" (exclamation point) button in your toolbar somewhere that will show you the output after the window has closed.

cin.get() does not clear the input buffer of carriage returns, so the next retrieval completes immediately. you can work around it by using the ignore methd cin.ignore('\n', 999); or something like that

Yes, but the window won't close.

or you can just flush the input buffer and then do cin.get()
