C Program to Generate Analog Clock Using Graphics

It is a sample C program to generate analog clock using graphics in c programming. You run this code and enter the time Hour, Minutes and Second and press Enter. You will get Analog clock that start from your set time.

Program Code
//C program For Analog Clock
#include<stdio.h>
#include<conio.h>
#include<graphics.h>
#include<math.h>
#include<dos.h>
main()
{
int gd=DETECT,gm;
int xm,ym,i,j,k,hrs,min,sec;
clrscr();
// Entering the correct and current time with verification
printf("Enter the current time\n Hours: ");
scanf("%d",&hrs);
printf("Minutes: ");
scanf("%d",&min);
printf("Seconds: ");
scanf("%d",&sec);

while (hrs<=0||hrs>12)
 {
 printf("Enter the correct hour:");
 scanf("%d",&hrs);
 }

while (min<0||min>=60)
 {
 printf("Enter the correct minute:");
 scanf("%d",&min);
 }

while (sec<0||sec>=60)
 {
 printf("Enter the correct second:");
 scanf("%d",&sec);
 }

//   Initilization of graphics mode
initgraph(&gd,&gm,"..\\bgi");
xm=getmaxx();
ym=getmaxy();

//   Generating the gasic outline of the clock
for(i=0;i<3;i++)         //   Drawing outer circle in dark
 circle(xm/2,ym/2,200+i);

setcolor(4);

for (i=-1;i<2;i++)      //Drawing the 2 vertical lines in thick
 {
 line(xm/2+i,ym/2-200,xm/2+i,ym/2-170);
 line(xm/2+i,ym/2+200,xm/2+i,ym/2+170);
 }

Why so complicated i have written simple code using functions. I will post that when i make some time.
This is also very good not but very very best buddy.
