Fungsi librari difftime() pada bahasa C

Fungsi pustaka pada bahasa c difftime() mengembalikan nilai berbeda, dalam hitungan waktu antara waktu mulai dan waktu akhir. (ending time-starting time)

// It is present in time.h header file

#include 

Sintak : 

double difftime(time_t time2, time_t time1);

Parameter:

time1 : Lower bound of the time interval

        whose length is calculated.

time2 : Higher bound of the time interval

        whose length is calculated.

Return value : 

Returns the difference between time1 and 

time2 (as measured in seconds).

// C program to demonstrate working of // difftime() #include <time.h> #include <stdio.h> #include <unistd.h> int main() { int sec; time_t time1, time2; // Current time time(&time1); for (sec = 1; sec <= 6; sec++) sleep(1); // time after sleep in loop. time(&time2); printf("Difference is %.2f seconds", difftime(time2, time1)); return 0; }

Output:

Difference is 6.00 seconds
