stop screen flickering

this need to be a maze for a game i need to have a stable display for the game i tried sleep function but rate of frame per sec still doesnt effect too much flickering

  int main()
{
	char Map[70][70]= {"#####################################################################",
		               "#      !                                                            #", 
                       "#                                                                   #",
	                   "#                                                                   #",
                       "#                                                                   #",
		               "#                                                                   #",
			           "#                                                                   #",
			           "#@                                                                  #",
			           "#####################################################################" };
	
	while (GameStatus == true)
	{
		system("CLS");
		for(int i=0;i<70;i++)
		{
			cout<<Map[i]<<endl;

And how do i set timer in this program

Using Sleep does not help in this case ,because at last the delay of the Sleep function ,ends your loop goes through another periode erase what's in the screen ,THAT'S THE FLICKERING

1 : so, when you gaming developping ,You need to wait for user typing commands(go right,go left ,fire...) You can do that with getch function

2 : The background does not need to be erased everytime ,only the sprite how gets erased and drawed

PS : why are you using 70 lines when you just need 9 ?Do you expect the hero going for walk outside the maze :)

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

using namespace std;

void gotoxy(int x,int y)
{
    COORD pos;
    pos.X = x;
    pos.Y = y;
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),pos);
}

void drawSprite(int x,int y)
{
    gotoxy(x,y);
    cout << '@';
}

void eraseSprite(int x,int y)
{
    gotoxy(x,y);
    cout << ' ';
}

int main()
{
    char Map[9][70]=
    {  "#####################################################################",
       "#      !                                                            #",
       "#                                                                   #",
       "#                                                                   #",
       "#                                                                   #",
       "#                                                                   #",
       "#                                                                   #",
       "#                                                                   #",
       "#####################################################################" };

    for(int i=0;i<9;i++)
    {
        cout << Map[i]<<endl;
    }

    int i=1;

	while(true)
	{
	    drawSprite(i,7);
		getch();
		eraseSprite(i++,7);

You could possibly use some of the things in the ctime header to create a timer.

or even

I've been trying to cut back on my replies to these kinds of posts...

... but you really should not be using the console for this. A program like this is MUCH easier to make with a graphics lib like SFML/SDL.
