How to make a digital clock using C

The following code creates a digital clock using a 1 sec. delay. <time.h> provides various functions to delay the time.
Source Code:

#include <stdio.h>
#include <time.h>
#include <windows.h>
COORD coord = {0, 0};
void gotoxy (int x, int y)
{
    coord.X = x; coord.Y = y; // X and Y coordinates
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}
void delay(unsigned int mseconds)
{
    clock_t goal = mseconds + clock();
    while (goal > clock());
}
void showClock(int x_1, int x_2, int x_3,int y){
    long i = 0;                      /* Loop counter              */
    clock_t now = 0;                 /* Holds initial clock time  */
    int interval = 1;                /* Seconds interval for o/p  */
    int elapsed = 0;
    int min=0,MIN=0,hrs=0,sec=0;
    int d=0,f=0;
    now = clock();
    /* Get current clock time    */
    for(i = 0L ;  ; i++){
        elapsed = (clock()-now)/CLOCKS_PER_SEC;
        if(elapsed>=interval){
            interval += 1;
            if(elapsed%60==0){
                min=elapsed/60;
                d=60*min;
                if(min%60==0){
                    hrs=min/60;
                    f=60*hrs;
                }
            }
            sec=elapsed-d;
            MIN=min-f;
            if(hrs<10){
                gotoxy(x_1,y);printf("0%d",hrs);
            }else{
                gotoxy(x_1,y);printf(":%d",hrs);
            }
            if(min<10){
                gotoxy(x_2,y);printf(":0%d",MIN);
            }else{
                gotoxy(x_2,y);printf(":%2d",MIN);
            }
            if(sec<10){
                gotoxy(x_3,y);printf(":0%d",sec);
            }else{
                gotoxy(x_3,y);printf(":%2d",sec);
            }
        }
    }
}
int main()
{
    showClock(2,4,7,4);
 return 0;
}
