7.16 LAB: Leap year - functions (OPTIONAL - EXTRA CREDIT)

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are:

1) The year must be divisible by 4

2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400

Some example leap years are 1600, 1712, and 2016.

a program that takes in a year and determines whether that year is a leap year.

Ex: If the input is:

1712 

the output is:

1712 is a leap year. 

Ex: If the input is:

1913 

the output is:

1913 is not a leap year. 

Your program must define and call the following function. The function should return true if the input year is a leap year and false otherwise.

bool IsLeapYear(int userYear)

Note: This is a lab from a previous chapter that now requires the use of a function.

The code I have so far

#include

using namespace std;

bool isLeapYear(int userYear)

{

bool isLeapYear;

if (userYear % 400 == 0)

{

isLeapYear = true;

}

else if(userYear%100 != 0 && userYear%4 == 0)

{

isLeapYear = true;

}

else

{

isLeapYear = false;

}

return isLeapYear;

}

int main ()

{

int userYear;

cin >> userYear;

if (isLeapYear(userYear) == true)

{

cout << userYear << " is a leap year." << endl;

}

else

{

cout << userYear << " is not a leap year." << endl;

}

return 0;

}
