I dont really understand your question, what is the error message that you get?
just a tip it's easier to read your code if you place it in code tags like this

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

main()
{
int r=1;
clrscr();
while (!kbhit())
{
gotoxy(30,r);
cout<<"welcome\a";
gotoxy(30,r); //go to x cordinate of column , y cordinate of row
clreol(); //clear end of line
r++;
if(r==24) r=1;
}
getch();
//system("pause");
}

how i can active code tags in DEV software, and there are 4 errors compiler showing in the above code. please explain it. thanx

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

main()
{
int r=1;
clrscr();
while (!kbhit())
{
gotoxy(30,r);
cout<<"welcome\a";
gotoxy(30,r); //go to x cordinate of column , y cordinate of row
clreol(); //clear end of line
r++;
if(r==24) r=1;
}
getch();
//system("pause");
}
i have enable code tag but its not copied here..

:D nevermind, I don't see "gotoxy" defined anywhere in your code...

#include <Windows.h>

typedef unsigned short ushort;

void gotoxy(ushort x, ushort y)
{
    HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    COORD Coord;
    Coord.X = x;
    Coord.Y = y;

    cout.flush();

    SetConsoleCurserPosition(hStdOut, Coord);
}

I'm not using Windows so not sure about Coord.X is short or unsigned short.

This is windows specific code, "conio.h" also is not a standard header.

@OP

Code tags are a formatting thing you use on this page, not elsewhere. Edit your post, then select your code, then press the <> button on the right on the format menu.

It would be easier if you post your compiler errors in full.

Sir here are the Error report of compiler:
