是一个判断输入的年份是不是闰年的程序 输入之后显示的是停止工作

#include<stdio.h>
int main()
{
    int year,leap;
    
    printf("enter year");
    scanf("%d",&year);  //&year
    
    if((year%4==0 && year%100!=0) || (year%400==0))
        leap=1;
    else
        leap=0;
    
    if(leap)
        printf("%d is a leap year.",year);
    else
        printf("%d is not a leap year.",year);
    
    return 0;
}
