计算机技术基础c语言课程设计潜艇大战

1、计算机技术基础课程设计C语言设计报告题目：简单潜艇大战一、选题背景：随着人们生活水平的提高，人们对精神生活的要求也随之提高了，当然，娱乐也成了人们生活中必不可少的一部分，为此，我用C语言编辑了一个简单的简单潜艇大战游戏程序。它操作起来简单方便，运行速度快。二、设计思想：简单潜艇大战就是玩家和电脑对战的游戏，玩家在确保本身不被敌人击中的情况下击中敌人则得分，若被敌人击中游戏结束。此程序利用了if,for,while等多种语句进行了编译，而且多次使用了for语句进行了循环，用if语句进行操作，if语句是用来处理条件选择的一种语句。此游戏可以任意移动玩家的位置。三、程序流程图开始图形初始化否否（敌人
