How to display a colorful animated string/phrase

#include<graphics.h>
#include<conio.h>
#include<stdio.h>
#include<dos.h>      // for delay() function


void main(void)
{
    int driver=DETECT, mode;
    int i;    //for loop
    initgraph(&driver, &mode, "c:\\TC\\bgi" );
    textcolor(BLACK);
    for(i=0;i<=400;i++)
    {
    clrscr();
    setcolor(i/15);     //set text/string color
    outtextxy(20+i,150,"**C Language Codes**");  //see the description below
    delay(30);       //slow down the loop
    }
    getch();
    closegraph();
}


What is outtextxy(); ?


It is a built-in function defined in the header file "graphics.h". This function used to display graphical string. The general syntax is as follows:
outtextxy(x-coordinate, y-coordinate, "String to display"); 


In the above program, outtextxy() function is put into for loop to make the text animated. As you can see that variable i is written with the x-coordinate whereas, the y-coordinate remains constant which means the text will move towards left to right on the screen.
