## C program to convert number of days to days, weeks, months and years

/** * C program to convert Numer of Days to * Year, Month, Week and Days */ #include <stdio.h> int main() { int inputDays, years, months, weeks, days; /* * Take number of days as input from user */ printf("Enter number of Days\n"); scanf("%d", &inputDays); /* * 1 Year = 365 Days, 1 Month = 30 Days, 1 Week = 7 Days * To keep things simple, We are not considering Leap years * and assuming 1 Month = 30 Days */ years = inputDays/365; // Remaining days after year inputDays = inputDays - years*365; months = inputDays/30; // Remaining days after month inputDays = inputDays - months*30; weeks = inputDays/7; // Remaining days after week inputDays = inputDays - weeks*7; days = inputDays; printf("Years : %d\n", years); printf("Months : %d\n", months); printf("Weeks : %d\n", weeks); printf("Days : %d", days); return 0; }

Output
