195. C Program to Find Your Age in Days.
How does this program work?
- This Program is used to find age in days.
- For this we need to first first check the year is leap year or not.
Here is the code
#include <time.h>
// Leap year checking
int leapYearFeb(int year, int mon)
{
int flag = 0;
if (year % 100 == 0)
{
if (year % 400 == 0)
{
if (mon == 2)
{
flag = 1;
}
}
}
else if (year % 4 == 0)
{
if (mon == 2)
{
flag = 1;
}
}
return (flag);
}
int main(void)
{
//Program to find the your age in days
int daysInMon[] = {31, 28, 31, 30, 31, 30,31, 31, 30, 31, 30, 31};
//Days in month
int days, month, year;
char dob[100];
time_t ts;
struct tm *ct;
days=13;
month=10;
year=1997;
printf("\nDate of Birth: %d/%d/%d", days, month, year);
ts = time(NULL); //Find the current month
ct = localtime(&ts);
printf("\nCurrent Date: %d/%d/%d",ct->tm_mday, ct->tm_mon + 1, ct->tm_year + 1900);
days = daysInMon[month - 1] - days + 1;
if (leapYearFeb(year, month))//Checking the given year Leap or not
{
days = days + 1;
}
//Calculating the num of year, month and date
days = days + ct->tm_mday;
month = (12 - month) + (ct->tm_mon);
year = (ct->tm_year + 1900) - year - 1;
if (leapYearFeb((ct->tm_year + 1900), (ct->tm_mon + 1)))
{
if (days >= (daysInMon[ct->tm_mon] + 1))
{
days = days - (daysInMon[ct->tm_mon] + 1);
month = month + 1;
}
}
else if (days >= daysInMon[ct->tm_mon])
{
days = days - (daysInMon[ct->tm_mon]);
month = month + 1;
}
if (month >= 12 )
{
year = year + 1;
month = month - 12;
}
//Output
printf("\nAge: %d year %d months and %d days", year, month, days);
return 0;
}
