Question

Hello, I need help with this homework assignment in C. Note that user input isn't required, how do you use the time() function to get the answer? The professor never explained and all the other programs here don't work.

You can find out how many seconds have elapsed since Jan 1, 1970 using the time() function.

#include <time.h>

now = time(NULL); // now is more than a billion seconds (which data type should you use?)

Write a program that estimates how many years, months, weeks, days, and hours have gone by since Jan 1 1970 by calculations with the number of seconds that have passed.

The number of months must be less than 12, i.e., take out how many years have gone by first, then how many months are left, then weeks, etc.

Assume that all years have 365 days, and all months have 30.42 days.

Explanation / Answer

#include "stdafx.h" //INCLUDE ONLY IF Visual Studio 2012 and above //CODE TESTED IN MS VSIUAL STUDIO #include #include int main () { time_t now; //number of seconds in a year,month,week ,day,hour time_t year=31536000; //60*60*24*365 time_t month=2628288; //60*60*24*30.42 time_t week = 604800; //60*60*24*7 time_t day= 86400; //60*60*24 time_t hour=3600; //current now = time (NULL); //calulcate time gone by time_t year2=now/year; now=now-(year2*year); time_t month2=now/month; now=now-(month2*month); time_t week2=now/week; now=now-(week2*week); time_t day2=now/day; now=now-(day2*day); time_t hour2=now/hour; now=now-(hour2*hour); printf ("Since January 1, 1970, %ld YEARS, %ld MONTHS, %ld WEEKS, %ld DAYS, %ld HOURS have gone by. ",year2,month2,week2,day2,hour2); return 0; }
