这道题你应该是判断是否是质数那里错了，我的程序是这样的

#include "stdio.h"

char a[110];

int f[30],x[110];

int main()

{

int max=0,min=100,n=0,i,j,ans;

scanf("%s",a);

for(i=0;i<=105;i++)

if(a[i]!='\0') n++;

else break;

for(i=0;i<n;i++)

f[a[i]-'a'+1]++;

for(i=1;i<=30;i++)

{

if(f[i]>max) max=f[i];

if(f[i]<min && f[i]) min=f[i];

}

ans=max-min;

for(i=2;i<=100;i++) x[i]=1;

for(i=2;i<=100;i++)

if(x[i])

for(j=i*2;j<=100;j+=i)

x[j]=0;

if(x[ans]) printf("Lucky Word\n%d",ans);

else printf("No Answer\n0");

return 0;

}

那个判断是否是质数那里要开一个数组标记的。。

咦不对。。你那个判断那个好像是对的
