Question

Write a program to simulate simple digital clock displaying

HOURS(s) : MINUTES(s): SECOND(s)

• How to get local system time ?

• How to split local system time into hours , minutes and seconds ?

Edit 1:

This is what I have tried, but its far from perfect (dosnt even use time.h)

     #include <stdio.h>
     #include <conio.h>
     #include <dos.h> void main() { int h,m,s; h=0; m=0; s=0; while(1) {

     if(s>59) {m=m+1; s=0; } 
      if(m>59) { h=h+1; m=0; } 
      if(h>11) { h=0; m=0; s=0; } 
      delay(1000); 
      s=s+1; 
      clrscr(); 
      printf("\n DIGITAL CLOCK");
      printf("\n HOUR:MINUTE:SECOND"); 
      printf("\n%d:%d:%d",h,m,s); 
}

}

time.h

#include <stdio.h>
#include <time.h>

int main(void) {

    time_t rawtime;
    struct tm*  time_;

    time(&rawtime);
    time_ = localtime(&rawtime);

    printf("%i:%i:%i %i %i %i\n", time_->tm_hour, time_->tm_min, 
            time_->tm_sec, time_->tm_mday, time_->tm_mon+1,
            time_->tm_year+1900);

    return 0;
}

Why did I do +1900 and +1 you can read here
