Marquee

[siddharth_1202]

I am trying to make a marquee, I have made this where the text maves from right to left and also where the text first moves left to right and then right to left.
What I am trying to do is that when the text moves from left to right it should come out one by one. For example
o
lo
llo
ello
Hello
Similarly the text should go out of the screen in the same manner
For example
Hello
Hell
Hel
He
H

The Coding for the same is

#include<iostream>
#include<dos.h>
#include<conio.h>
class marquee
{
	int a,b,x,y,z;
	char c[50];
	public:
	void display()
	{
		cout<<"\nPlease Enter your Name:";cin>>c;
		cout<<"\nEnter a Choice. 1 for Rotating and 2 for Bouncing: ";cin>>z;
		for(y=0;c[y]!='\0';y++); 
		if(z==2)
		{
			for(x=1;x>0;x++)
			{
				for(a=1;a<80-y;a++)
				{
					for(b=1;b<=a;b++)
					{
						clrscr();
						cout<<" ";
					}
					cout<<c<<"\n";
					delay(50000000);
				}
				for(a=80-y;a>y;a--)
				{
					for(b=1;b<=a;b++)
					{
						clrscr();
						cout<<" ";
					}
					cout<<c<<"\n";
					delay(50000000);
				}
			}
			clrscr();
		}
		else if (z==1)
		{
			for(x=1;x>0;x++)
			{
				for(z=1;z<=x;z++)		\\Starting
				{
					cout<<c[y];y--;
				}
				for(a=1;a<80-y;a++) 		\\Middle
				{
					for(b=1;b<=a;b++)
					{
						clrscr();
						cout<<" ";
					}
					cout<<c<<"\n";
					delay(50000000);
				}
			}
			clrscr();
		}
		else
		cout<<"\nERROR!!!\nYou have entered a wrong choice. Run the program again.";
	}
};
void main()
{
	marquee view;
	view.display();
