Press any key to continue

[Bob Altman]

Hi all,

I have an unmanaged console app written in C++. I can't figure out how to
get C++ to do the standard issue "press any key to continue" thing:

cout << "Press any key to continue: ";
cin >> <your code goes here>;

TIA,

- Bob

Here's one approach...

char cont;
cout << "Press Enter to continue.\n";
cin.get(cont);
// whatever is next...

Try this:

#include <iostream>

using namespace std;

int main()
{
std::cout << "Hello, world!" << std::endl;

system("pause") ;
}

I know it works in std C++ - unmanaged. If any one knows for managed wrapper
please post it.

Thank you both! The first approach [cin.get()] serves the intended purpose,
but requires that the user press ENTER. The second approach
[system("pause")] does exactly what I wanted, but it's seriously
non-portable.

As an exercise for my own education, let me rephrase the question. Suppose
I have an application that allows the user to enter a command by pressing a
single key on the keyboard. How would I accept the command into a char
variable?

1) getch(), that's for plain C ;)

2) Maybe this:

char ch;
cin >> ch;

I don't think you can do this portably in C++.

There isn't a portable solution. You either must accept key+enter or resort to
non-portable/platform-specific solutions.
