A leap year is a calendar year in which an additional day is added to February month. In a leap year, the number of days in February month and the year are 29 and 366 respectively. A year that is not a leap year is called a common year. A year is said to be a leap year if
In the below example, conditional statements are used to identify a leap year.
#include <iostream>
using namespace std;
int main() {
int year = 2019;
if (year % 400 == 0) {
cout<<year<<" is a leap year.";
} else if (year % 100 == 0) {
cout<<year<<" is not a leap year.";
} else if (year % 4 == 0) {
cout<<year<<" is a leap year.";
} else {
cout<<year<<" is not a leap year.";
}
return 0;
}
2019 is not a leap year.
In the below example, a function called leapyear() is created which takes year as argument and prints whether the passed year is a leap year or not.
#include <iostream>
using namespace std;
static void leapyear(int);
static void leapyear(int year) {
if (year % 400 == 0) {
cout<<year<<" is a leap year.";
} else if (year % 100 == 0) {
cout<<year<<" is not a leap year.";
} else if (year % 4 == 0) {
cout<<year<<" is a leap year.";
} else {
cout<<year<<" is not a leap year.";
}
}
int main() {
leapyear(2019);
return 0;
}
2019 is not a leap year.
