为什么这个程序提示runtime error

#include <iostream>
#include <cstring>
using namespace std;
int book[100001];
int PRIME() {
    for (int i = 2; i <= 100000; i++) {
        if (book[i] == 0)
            for (int j = i * 2; j <= 100000; j += i) {
                book[j] = 1;
            }
    }
}
int main() {
    int n;
    cin >> n;
    PRIME();
    for (int i = 2; i <= n; i++) {
        if (book[i] == 0)
            cout << i << ' ';
    }
    return 0;
}

给出运行截图

试运行了下，没出现题主的错误。
