\号改%号。printf括号里&号去掉撒。最后还要记得加大括号啊！
#include "Stdio.h"
#include "Conio.h"

int main(void)
{

int ch;
printf("Please enter a year:");
scanf("%d",&ch);
if((ch%4==0&&ch%100!=0)||(ch%400==0))
printf("%d is a leap year\n",ch);
else
printf("%d is not a leap year",ch);


  getch();
  return 0;
}

汗，错误还真是挺多的 ，不过都是些小错误！ 以后我也得多注意了！ 学习了！

试试这个，我用VC6。0调试过没有错误！
#include<stdio.h>
void main()
{
    int year,leap;
    leap=0;
    printf("input year:");
    scanf("%d",&year);
    if(year%4==0&&year%400!=0||year%400==0)
        leap=1;
    else
        leap=0;
    if(leap=1)
        printf("%d is a leap year!\n",year);
    else
       printf("%d is a not leap year!\n",year);
}

/和%要分清呀，LZ

#include "Stdio.h"
#include "Conio.h"

int main(void)
{

int ch;
printf("Please enter a year:");
scanf("%d",&ch);
if((ch%4==0&&ch%100!=0)||(ch%400==0))
printf("%d is a leap year\n",ch);
else
printf("%d is not a leap year",ch);


  getch();
  return 0;
}
%与/分清一下啊~~后面多加了两个&，最后就是少了个}
