Write a program that takes a year as the input from stdin and uses the modulus operator to determine if the year is a leap year or not. Print the result to the screen.

Here is the algorithm to check if a year is a leap year or not:

if $($year is not divisible by $4)$ then $($it is a common year$)$

else if $($year is not divisible by $100)$ then $($it is a leap year$)$

else if $($year is not divisible by $400)$ then $($it is a common year$)$

else $($it is a leap year$)$

Here is what I have so far:

#include

int main$($void$)$

$\{$

int year;

char c;

printf$("$Enter a year: $")$;

$//$use scanf to accept user input

$//$check that expected data type was included in the user input

$//$check that nothing else after the valid user input was included

$//$use while loop to iterate forever until valid inout is received

while$(($scanf$("\%$d$",$ &year$)!=1)||(($c $=$ getchar$())!=\text{'}$

$\text{'}$ && c $!=$ EOF$))$

$\{$

printf$("$ERROR: Invalid input. Please enter new value: $")$;

while $(($c $=$ getchar$())!=\text{'}$

$\text{'}$ && c $!=$ EOF$)$; $//$ flush input buffer before next scanf$()$

$\}$

$//$ TO DO: determine if input year is a leap year

if$($year $\%4!=0)$

$\{$

printf$("\%$d is not a leap year.

$")$;

$\}$

return $0$;

$\}$
