#include
main()
{
int year;
scanf("%d",&year);
if((year%4==0 && year%100!=0)
printf("%d is a leap year\n",year);
else if (year%400==0))
printf("%d is a leap year\n",year);
else
printf("%d is Not a leap year\n",year);
}

自己对照看吧前面两个if都少了或多了一个括号，另外main前面加void，因为它没返回值。虽然不加也OK，但会有警告。从开始就要养成好习惯嘛 #includevoid main(){ int year; scanf("%d",&year); if(year%4==0 && year%100!=0)printf("%d is a leap year\n",year);else if ((year%400==0))printf("%d is a leap year\n",year);else printf("%d is Not a leap year\n",year)

我看到了语法错误,if和else if 的括号错了，改成这样#includemain(){
int year;
scanf("%d",&year);
