All most all
game/graphics library provides timing function but If you create a game such as
puzzle games or quiz games without graphics then you have to write your own
procedure. In C programming language time.h library function is available to
access clock time. Here I have provided a sample digital timer application
written in C using time.h library function.
#include <stdio.h>
#include <time.h> //this is header file for time
#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());
}
int main()
{
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(2,4);
printf("0%d",hrs);
}
else
{
gotoxy(2,4);
printf(":%d",hrs);
}
if(min<10)
{
gotoxy(4,4);
printf(":0%d",MIN);
}
else
{
gotoxy(4,4);
printf(":%2d",MIN);
}
if(sec<10)
{
gotoxy(7,4);
printf(":0%d",sec);
}
else
{
gotoxy(7,4);
printf(":%2d",sec);
}
gotoxy(7,7);
printf("%dhrs:%dmin:%dsec",hrs,MIN,sec);
}
}
return 0;
}
