In C++: Write a function which calculates leap years. The function prototype is as follows:

In C++:The function prototype is as follows:bool leap_year(int year);Write the function body which returns true if the year is a leap year and false if the year is not a leap year.A leap year is defined as any year divisible by 4 with the following exception:Years that are evenly divisible by 100 are not leap years, unless they are also evenly divisible by 400Also note that any year prior to 1582 is not a leap year.Your submission should include a fully functional program including a main program that tests your leap_year function.

#include<iostream.h>#include <stdio.h>#include<conio.h>enum bool { false, true };bool leap_year(int year);void main(void) {int year;int isLeapYear;clrscr();...
