10194 - Football (aka Soccer)

本文主要是介绍10194 - Football (aka Soccer)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

题目：10194 - Football (aka Soccer)

题目大意：给你一些比赛记录，然后让你依据要求这些排序：

1. Most points earned. （得分胜利3，平局1，失败0）
2. Most wins.
3. Most goal difference (i.e. goals scored - goals against)
4. Most goals scored.
5. Less games played.    （比赛次数越少越好）
6. Lexicographic order. （不区分大小写排序）
7. 解题思路：就是按照这些要求写比较函数，用sort排序，然后输出即可。注意：scanf（）是不舍弃回车，需要ch = getchar（）接受回车，而gets或getline是可以舍弃回车的。然后要细心。数组不要越界，越界了不仅可能RE还有可能WA。两个数据组之间要有一个空白行。
