3个空瓶换一瓶新酒的小问题

题目：共有1000瓶啤酒，每喝完一瓶得到一个空瓶子，每3个空瓶子又能换1瓶啤酒，喝掉以后又可以得到一个空瓶子，问总共能喝到多少瓶啤酒，最后还剩余多少个空瓶子？

用C++简单写了一个：

#pragma region Quiz requirements// The Quiz is to calculate the number of bottles:// There are 1000 bottles of beer, 3 empty bottles can // trade for another additional beer// How many bottles will it be and how many empty// bottles will be left?#pragma endregion#include <iostream>using std::cout;using std::endl;int main(){int total = 1000;int full = 1000;int empty = 0;for(full=1000; full >0 ; full--) // stop until you finish every full beer bottle available{++ empty;if(empty == 3){empty = 0;++ full;++ total;}}cout << "Total number of bottle is: " << total << endl;cout << "Total empty bottle left is: " << empty << endl;return 0;}

 最的的结果如下：
