送分，还是送分！！！！！！！！！！！（关于足球比赛的赛程生成）

[HasanSas]

如果某联赛现有18只球队，怎样随即生成全部主客场2回合306场比赛？？？
要求每轮显示9场比赛，各位高手如能提供源代码或者思路的都有分，谢谢了

随即？随机？

#include <iostream>
#include <vector>
#include <algorithm>

typedef std::vector<int> int_array;

int main()
{
int team_count;//队伍总数
std::cin >> team_count;
int virtual_team_count = team_count;//虚拟队伍数，保证是偶数
if (virtual_team_count % 2 != 0)
++virtual_team_count;
int turn_count = virtual_team_count - 1;//比赛轮数
int game_count_per_turn = virtual_team_count / 2;//每轮的比赛数
int_array game_numbers(virtual_team_count);//所有的队伍号码
for(int i = 1; i <= team_count; ++i)
game_numbers[i - 1] = i;
if (virtual_team_count != team_count)
{
std::rotate(game_numbers.begin() + virtual_team_count / 2, game_numbers.end() - 1, game_numbers.end());
game_numbers[virtual_team_count / 2] = 0;//虚拟的队伍号码为0
}
//如果要“随机”，加下下面这句
//std::random_shuffle(game_numbers.begin(), game_numbers.end());
for (int i = 1; i <= turn_count; ++i)
{
std::cout << "第" << i << "轮:";
for (int j = 1; j <= game_count_per_turn; j ++)
{
std::cout << "<" << game_numbers[j - 1] << "," << game_numbers[virtual_team_count - j] << "> ";
}
std::cout << std::endl;
std::rotate(game_numbers.begin() + 1, game_numbers.end() - 1, game_numbers.end());
}
}
