DOS app question

[Michael Huntwork]

Hello,

I am new to C++ and am taking my first class and in my programs I
would like to add a non-required feature.

I would like for my app to not close immediately after completion in
Windows when starting it via the ol' double click.

I know that if I start it from a DOS prompt everything will work out
just fine but I and several others would like to "improve" our
projects.

Any suggestions?

Thanks,

Mike

Add "system("pause");" at the point you require your program to display a
"Press any key to continue ... " sort of prompt.

HTH,

Remember that this is not a very portable way of doing this since "pause" is
a DOS command which displays something to the effect of "Press any key to
continue ... ". Using pause will not work on Linux, etc.

OFF-TOPIC

Read in a string at the end of your code. Or (since it seems to be for
Windows only) include <stdlib.h> (not stdlib, which would be C++, MS
compilers had problems with putting everything to std namespace) and call
system("pause"); at the end of your program. (This is a non-portable little
hack!)

Please note, that your question has nothing to do with the C++ language!

#include <iostream>

int main()
{

/* your code */

std::cout << "Press return to continue";
std::cin.get();
return 0;
}

This will only work for platforms which have such a 'pause'
command, and that it does what the OP asks. I.e. it's a non-
portable solution. See my post this thread for a portable
solution.
