updating the screen

[Acidburn]

Hello,

I recently programed a hangman game, However it as flaws with are buggin me! Basically you sak the user for a guess, then the outcome is displayed... then I've cleared the screen and redraw / reload it. This wouldnt be done in the real world since rendering would take too long. Ok its not really an issue in this case, but I'd like to know how to render the screen rather than use

system("cls") and go through it all again.... does that make sence?

well this is an example :

#include <iostream>

using namespace std;

int main()

{
long int i = 0;
cout << "|" <<endl;
for (i = 0; i < 550000000 ; i++)
{}
system("cls");

cout << "/" << endl;
for (i = 0; i < 550000000 ; i++)
{}
system("cls");

cout << "-" <<endl;
for (i = 0; i < 550000000 ; i++)
{}
system("cls");








return 0;

}

However it consists of "cls" which is a danger! It would in the real world take to long to redarw elements that have not changed! So is they a way to draw only elements that have?

There is no way to do that using just good ol C++. You would have to go into system dependent console stuff. If you are using windows check out this site for a look into how to do some window console specific stuff.
