@[908671152czy](/space/show?uid=76682) 还有，你怕是傻了，为什么要加system("pause")啊，那不是调试才用的吗，

@[2016c01](/space/show?uid=5880) 改完以后依旧gg，全WA
```cpp
#include<stdio.h>
#include<math.h>
int judgeprime(int n);
int main()
{
char c;
int a[26] = { 0 }, maxn, minn, cnt = 0, d = 0, i;
maxn = a[0];
minn = 1;
c = getchar();
while (c != '\n')
{
if (c > 'a'&&c < 'z')
d = c - 96;
a[d]++;
c = getchar();
}
for (i = 1; i < 26; i++)
{
if (a[i] > maxn)
maxn = a[i];
else if (a[i] < minn&&a[i] != 0)
minn = a[i];
}
if (judgeprime(maxn - minn))
printf("Lucky Word\n%d", maxn - minn);
else
printf("No Answer\n0");
system("pause");
return 0;
}
int judgeprime(int n)
{
int cnt = 2, prime = 1;
for (cnt = 2; cnt < fabs(n); cnt++)
{
if (n%cnt != 0)
prime = 0;
}
if (n == 0 || n == 1)
prime = 0;
return prime;
}
```

@[908671152czy](/space/show?uid=76682) 你不知道如果用system("pause")会输出“请按任意键继续...”吗，难怪会错
by B_Qu1e7 @ 2017-12-13 17:50:23
@[908671152czy](/space/show?uid=76682) 根本就是system("pause")的错，那是调试才用的

@[2016c01](/space/show?uid=5880) 我用的是VS2017，如果不加system（“pause”），看不到结果，会闪退的。我试试，我把那个去掉再交。原先都是用codeblock，今天改用了VS2017.

@[908671152czy](/space/show?uid=76682) 额你没有用C++吗
by B_Qu1e7 @ 2017-12-13 17:53:33
写C可以用C++5.11编译@[908671152czy](/space/show?uid=76682)

@[908671152czy](/space/show?uid=76682) 还有，你函数怕是用错了，fabs是求浮点数的绝对值，又没有浮点数，用fabs干嘛，这里应该是sqrt，开方吧

@[2016c01](/space/show?uid=5880) 好像是。。。。萌新记混了。。至于编译器我也不是了解很多，大一新生很懵逼啊
