What are the algorithm in stopwatch c language?

Answer 1

#include <stdio.h>

#include <time.h>

int main()

{

time_t start_time;

time_t stop_time;

int e;

clrscr();

printf( "Type the Enter key to START timing.\n");

while(getchar()!='\n');

start_time=time(NULL);

printf( "Type the Enter key to STOP timing.\n");

while(getchar()!='\n');

stop_time=time(NULL) ;

e=difftime( stop_time,start_time);

printf( "Elapsed time: %d seconds.\n" ,e) ;

getch();

}

Answer 2

#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);

}

}
