Write a C program to convert days into months and days.
int main() {
/* no of days in every months(from Jan - Dec) */
int daysInMonth[] = {31, 28, 31, 30, 31, 30,
31, 31, 30, 31, 30, 31};
int days, month = 0, flag = 1, i;
/* get the no of days from user */
printf("Enter the number of days:");
scanf("%d", &days);
/*
* if days count is less than 31,
* return days value as such
*/
if (days < 31) {
printf("Number of days is %d\n", days);
return 0;
}
printf("%d days = ", days);
/* calculate no of months */
while (1) {
for (i = 0; i < 12; i++) {
month++;
days = days - daysInMonth[i];
if (days < daysInMonth[i + 1]) {
flag = 0;
break;
}
}
if (!flag)
break;
}
/* print no of days and months */
printf("%d Months and %d days\n", month, days);
return 0;
}
Output:
jp@jp-VirtualBox:~/$ ./a.out
Enter the number of days:100
100 days = 3 Months and 10 days
Enter the number of days:100
100 days = 3 Months and 10 days
