There is no reason to post all of that code to ask that question. I suppose you need to handle/trap a keypress event and manually output a *, but I'm not sure how to do that.

I've changed the code from the link Ancient Dragon posted, it's still not complete, but it's more useful ...

#include<iostream>
#include<string>
#include<conio.h>

using namespace std;

int main()
{
	string userinput;
	char cchar;
	int cint;

	cout << "Enter password: ";

	for(int i=0; ; i++ ){
		cchar = getch();
		cint = cchar;
		if(!(cint == 13)) /* ENTER WAS PRESSED */
		{
		    userinput = userinput + cchar;
		    putch('*');
		} else {
		    break;
		}
	}

	if(userinput == "password")
	    cout << "\nPassword accepted.\n";
	else
	    cout << "\nAccess denied.\n";

	return 0;
}
