Text Animation in C/C++

Hey guys, in this article, I'm going to let you know a method which is defined inside of `conio.h` , and then how this method helps to achieve this. 

As I told this is a predefined method which is defined inside "conio.h" header file.

Declaration:

void window(int left, int top, int right, int bottom);

window defines a text window on-screen, which means you can display your statements or text on located space on the window (o/p) screen.

there are 4 parameters required for specifying the coordinates to display the text on the window screen,

Example

#include <conio.h>

#include <dos.h>

int main() {

  int i;

  for (i = 25; i >= 1; i--) {

    clrscr();

    window(20, i, 70, 25);

    textcolor(2);

    cprintf("This program intruduced by Abdul Rizwan\r\n\n");

    delay(500); // halt for half second [1000 = 1second]

    if (i == 1)

      i = 25; // reinitialize of i

  }

  return 0;

}

 here as I defined window(20, i, 70, 25)

• [ 20 (left),  i (top) ] : this will start from 20 left and i=25 (top) coordinator, [which means it will start from the bottom of window screen] and i(top) is decreased by one until i!=0.
  
  
• [70 (right), 25(bottom) ]: 70 is the maximum length of the screen right coordinator, upto 70 that statement can be displayed, means your text will start from 20 and its range is 70 [upto 70 cols this text will be displayed] and 25 is bottom coordinate as I have given the input value.

        

To understand this concept, would like to recommend you to write your own program and test it. Thanks
