Digital Clock Using "C"

This is Very simple

there is an header file called "dos.h" which contains predefined structures for time and date.
So i have declared here two variables of type

struct date d;
struct time t;


to get the current system date and time call function getdate() & gettime() where these functions take date , time respectively.

getdate(&d);
gettime(&t);

PredefinedStructures :
date:
struct date {

int da_year; /* current year */
char da_day; /* day of the month */
char da_mon; /* month (1 = Jan) */

};

time:
struct time {
unsigned char ti_min; /* minutes */
unsigned char ti_hour; /* hours */
unsigned char ti_hund; /* hundredths of seconds */
unsigned char ti_sec; /* seconds */
};

void main()
{

gettime(&t);

gotoxy(23,24);
cprintf("Date(dd/mm/yy) : %d/%d/%d",d.da_day,d.da_mon,d.da_year);
gotoxy(23,26);
cprintf("Time(hr/min/sec) : %d/%d/%d",t.ti_hour,t.ti_min,t.ti_sec);

}
while(!kbhit());
}
