This is a c program to display a digital clock showing correct time. It reads time at 1 second interval and displays it on the screen. To know how to get date and time in C, see this post: How to Get Time and Date in C - C Program to Read and Display Time and Date

#include<stdio.h>
#include<graphics.h>
#include<time.h>
int gd=DETECT,gm,x,y;

void main()
{
time_t now;
struct tm *timeinfo;
initgraph(&gd,&gm,"..\\BGI\\");
x=getmaxx()/2-80;
y=getmaxy()/2-20;

while(!kbhit())
 {
 time(&now);
 timeinfo=localtime(&now);
 printf("%2d : %2d : %2d",timeinfo->tm_hour,timeinfo->tm_min,timeinfo->tm_sec);
 delay(1000);
 cleardevice();
 }
getch();
