Bro, try this

#include <iostream>
using namespace std;

int main()
{
    int t;
    cin >> t;
    while (t--)
    {
        int num, flag = 0;
        cin >> num;
        for (int i = 2; i < num; i++)
        {
            if (num % i == 0)
            {
                flag = 1;
            }
        }
        if (num == 1)
        {
            cout << "no" << endl;
        }
        else
        {

            if (flag == 1)
            {
                cout << "no" << endl;
            }
            else
            {
                cout << "yes" << endl;
            }
        }
    }
    return 0;
}
