Showing a Clock on the screen using C Language

Problem: How to show continuous time on the screen   

Solution

To show continuous time on the screen we can use gettime() function. gettime() function accepts a structure variable reference. Here we use structure type time to provide this reference.   The programming code for showing continuous time is given below→

 

#include<stdio.h>

#include<conio.h>

#include<dos.h>

void main()

{

 struct time t;

 do

 {

  clrscr();

  gettime(&t);

  gotoxy(30,10);

  textcolor(2);

  cprintf("Time: %2d:%02d:%02d",t.ti_hour, t.ti_min, t.ti_sec);

  delay(1000);

 }while(!kbhit());

}

Output

Remark

This is a program to show continuous time until a key is pressed. If we want to show a clock on the screen then we can use this program.
