#include<bits/stdc++.h>
using namespace std;

int main()
{
	int l,time1 = 0,all = 0,number = 2;	//time1用来存有几个质数，all用来和l比较大小，number用来从2开始向上枚举所有质数
    cin>>l;
    while(all<l)	
    {
        int a = 0;
        for(int i = 1;i<=number;i++)
        {
            if(number%i == 0)
            {
                ++a;
            }
        }
        if(a == 2)
        {
            cout<<number<<endl;
            all+=number;
            ++time1;
        }
        ++number;
    }
    cout<<time1;
	return 0;
}

可过一组样例,请就我的代码来回答，thanks
