编写一个程序,判断输入的年份是否为闰年

#includemain(){int t;int is(int t);printf("输入年份为");scanf("%d\n",&t);t=is(t);if(t=1)printf("%d是闰年",t);else printf("%d不是闰年",t);}int is(int year){if((year%4==0&&year%100!=0)||year%400==0)return 1;elsereturn 0;}第二个#include void main(){int n;printf("输入年份:");scanf("%d",&n);if((n%4==0&&n%100!=0)||(n%400==0))printf("%d是闰年\n",n);else printf("%d不是闰年\n",n);}
