int x,y,z,a,n,o,m,c,d;
{
for(x=1;x<=1;x++)
{
//first line upper
for(y=15;y<=64;y++)
{
gotoxy(y,x=5);
textbackground(4);
cout<<'_';
delay(50);
}
}
//second line right side
{
for(z=6;z<=20;z++)
{
gotoxy(x=65,z);
cout<<'|'<<endl;
delay(50);
}
}
{
//fourth line bottom
for(m=64;m>=15;m--)
{
gotoxy(m,x=20);
cout<<'_';
delay(50);
}
}
//third line left side downward
