CLOCK PROGRAM

his is clock program which resembles a wall clock. There are two versions of the program, one directly displays the clock and the
other has a little graphical introduction.
This clock program takes the time from the system when it is executed and from then it ticks for each second until any key is hit.

Code :
#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
#include<graphics.h>
#include<dos.h>
#include<math.h>
void main()
{

 int i,j,k,s,m,h;
 intro();
 settextstyle(DEFAULT_FONT, HORIZ_DIR, 1);
 drawclock();
 gettime(&t);

 if(t.ti_sec>15)
   s=360-((t.ti_sec-15)*6);
 else
   s=90-(t.ti_sec*6);

 if(t.ti_min>15)
   m=360-((t.ti_min-15)*6);

 else if((t.ti_hour>=13)&&(t.ti_hour<=23))
   h=360-((t.ti_hour-15)*30)-((t.ti_min/12)*6);
