用C语言设计一个求闰年的方法?

!=0 || year%400==0)
{
printf (".h"
if (year%4==0 && year%100;n"%d是闰年\),year);
}
else
printf (",&year);
pritnf (",year);
main()
{
int year;stdio: "%d"
scanf (";输入一个年份;%d不是闰年\n"#include "

scanf(");;stdio,year);
#include <.h>!"%d"}
else
{printf("
printf("math,year); bu shi rui nian;shi rui nian;%d"%d";;
printf(");
main ()
{ int year.h":"
if((year%4==0&&year%100,&year)!"请输入一个年份;
printf(")!=0)||year%400==0)
{printf("#include "

!=0 || year%400==0)
{
printf (".h"
if (year%4==0 && year%100;n"%d是闰年\),year);
}
else
printf (",&year);
pritnf (",year);
main()
{
int year;stdio: "%d"
scanf (";输入一个年份;%d不是闰年\n"#include "
