C語(yǔ)言如何實(shí)現(xiàn)歌手比賽系統(tǒng)

這篇文章主要講解了“C語(yǔ)言如何實(shí)現(xiàn)歌手比賽系統(tǒng)”，文中的講解內(nèi)容簡(jiǎn)單清晰，易于學(xué)習(xí)與理解，下面請(qǐng)大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“C語(yǔ)言如何實(shí)現(xiàn)歌手比賽系統(tǒng)”吧！

一、項(xiàng)目簡(jiǎn)介

對(duì)一次歌手比賽的成績(jī)進(jìn)行管理
輸入每個(gè)選手的數(shù)據(jù)包括編號(hào)、姓名、十個(gè)評(píng)委的成績(jī)，根據(jù)輸入計(jì)算出總成績(jī)和平均成績(jī)（去掉最高分，去掉最低分）。

二、任務(wù)概述

要求歌手比賽系統(tǒng)實(shí)現(xiàn)對(duì)學(xué)生基本信息（如編號(hào)、姓名、性別等）及十個(gè)評(píng)委的成績(jī)的管理（增加、刪除、修改或更新、查詢、統(tǒng)計(jì)、保存到文件、從文件裝載等操作）。

三、功能展示

四、思維導(dǎo)圖

五、程序源碼
