大概率是我根本不会整除吧
算了，请求DALAO帮忙~

垃圾代码~~

#include<iostream>
#include<cmath>
using namespace std;
int main() {
	int n = 0, b = 0, last = 0;  //初始化变量
	bool a = true;   //这个判断i是否为质数，是则为true
	//printf("%d", &n);
	cin >> n;
	for (int i = 2; i <= n; i++) {
		//cout << i << " " << 9 << endl;  
		for (int j = 2; j < i; j++) {
			//cout << i << " " << 11 << endl;
			//cout << i << " " << j <<endl;
			if (i % j == 0) {
				a = false;
			}
		}
		if (a) {
			last = i; //上一个质数
			//cout << i << " " << 16 << endl;
			if (b <= n) {	//判断是否超限
				//cout << i << " " << 17 <<endl;
				b++; 
			}
			else {  
				cout << i - last << endl << b;//输出最后一个没有超限的质数
			}
		}
		a = true;
	}
	return 0;
}

望DALAO忍住骂我的欲望
放过我玩这个小小白吧 求指出错误，谢谢~
