problem on getchar()...

[MargNat]

Hi,
I've wrote a simple c++ program without graphic interface;
Now, if I build it with Visual Studio function getchar() works in a
way;
if I build it with Dev-C++ function getchar() works in another way.
Why?

Then, another question:

Is there a specific function to exit program pressing any button?
I've tried this with getchar() function, but after I press a button, I
must press Enter too.

Thank you.

If I want the user to press Enter, then I do:

std::string trash;
std::getline(std::cin, trash);

Of course, this requires #include <string>. It only requires the user
to press Enter, and does not require pressing another key before it.

Why what? You haven't shown any code or told us what "a way" and
"another way" mean. The crystal ball is in the shop this week.

getchar() is a macro rather than a function. This means there
is more likely to be inconsistent behavior, depending on how
you call it and depending on your system. Try using fgetc()
instead.
