#include <stdio.h> main() { int year,leap; scanf ("%d",&year); if((year%4=0&&year%100!=0)||(year%400=0)); else leap=0

if (leap) printf("%d is leap year",year) ; else printf ("%d is not a leap",year); } 这个逻辑表达式到底错在哪里在啊？？？？ 还望各路大侠指点迷津。

帮你改过来了,不过这个程序不是很好! #include <stdio.h> void main() { int year,leap; printf("please enter the year:"); scanf ("%d",&year); if((year%4==0&&year%100!=0)||(year%400==0)) leap=1; else leap=0;

if (leap==1) printf("%d is leap year\n",year) ; else printf ("%d is not a leap\n",year); getch(); }
