Source Code

#include <iostream.h>
#include <conio.h>
bool passcheck(void) //checks password WITHOUT displaying the characters on-screen
{
	char password[7] = "outlaw"; //[] can be used instead, but it takes more memory, its quicker than counting though
	int plen = 6; //plen must be the number of letters in password
	char let;
	for(int i = 0; i < plen; i++)
	{
		let = getch();
		if(password[i] != let)
			return false;
	}
	return true;
}
//the above code immediately returns false if an incorrect password is imput
//if you want it to only return false at the end of the password, create a seperate bool variable
//to be returned at the end of the program
//instead of a for statement you can use (while x != 13) and hit enter at the end of the password
//(13 is the ascii value of enter)
