# Mini calendar solve

umm, this is my code, after remake cause the last one didnt work (i dont know why :)) ), hope it can help u <3

• i write code in VS so it need #define _CRT_SECURE_NO_WARNINGS to use scanf.

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdbool.h>

//days in month
int days_in_month[13] = { 0,31,28,31,30,31,30,31,31,30,31,30,31 };

//check leap year
bool is_leap_year(int year) {
if (year % 4 == 0 && (year % 100 != 0 || year % 400 == 0)) {
return true;
}
else {
return false;
}
}
//add some days to a date function
int days_left_in_month = days_in_month[*mm] - *dd;

``````while (days_left_to_add > 0) {
if (*mm == 2 && is_leap_year(*yy) == true) {
days_left_in_month += 1;
}
*dd = 1;
if (*mm == 12) {
*mm = 1;
*yy += 1;
}
else {
*mm = *mm + 1;
}
}
else {
}
}
``````

}

int main() {
//check leap year
printf(“Please enter a date between the years 1800 and 10000 in the format mm dd yy and provide the number of days to add to this date:\n”);
printf(“date:”);
scanf(“%i%i%i”, &mm, &dd, &yy);

``````if (is_leap_year(yy) == true) {
printf("Leap year\n");

}
else {
printf("Not leap year");
}
