@[hellowcworld](/user/798884) $n = 1$ 也不是质数

@[hellowcworld](/user/798884) 改成这样就过了
```cpp
#include<iostream>
#include<cmath>
bool isprime(unsigned int n);
using namespace std;
int main()
{
int n;
cin>>n;
unsigned int number[n];
for(int index=0;index<n;index++)
cin>>number[index];
for(int index=0;index<n;index++)
{if(isprime(number[index])) cout<<number[index]<<" ";}
return 0;
}
bool isprime(unsigned int n)
{
bool jud=true;
if(n==0||n==1) //更改了这里
jud=false;
else for(int i=2;i<=sqrt(n);i++)
{
if(n%i==0)
jud=false;
}
return jud;
}
```
