In C++:

Here are three definitions:

a. Def: A year y is a century year if y is divisible by 100. Example: y=300 is a century year, but y=150 is not.

b. Def: A year y is a non-century year if y is not a century year. Example: y=150 is a non century year. Y=4 is a non-century year.

c. Def: a year y is a leap year if it is a non-century year that is divisible by 4, or a century year that is divisible by 400. Nothing else is a leap year. Example: y=4 is a leap year, y=100 is not a leap year, y=400 is a leap year.

Question: a Write a function

bool leapyear(int y)

that when passed a year y will return true if y is a leap year and false if not.
