Win32 How to have Text Box output a variable

Question

I have created a text box through CreateWindowEx and mostly understand how to. Now i'm attempting to do the same thing, but outputting text from a variable, for example.

int main
{
	int x = 20
	std::cout << "You have " << x << " cats\n";

	return 0;
}

Answer 1

For example, with an Edit control with ID = 12 :

int n = 20;
SetDlgItemInt(hWnd, 12,	n, FALSE);
