c++ - 摇滚/纸/剪刀游戏无法正常运行
问题描述
我正在上计算机科学的初级课程,我的下一个项目应该是制作一个石头、纸、剪刀游戏。
游戏还没有完成,因为我仍然需要添加记分和输入建议(哦,我应该更频繁地选择)和循环。
然而,我的问题是,我想测试游戏是如何运行的,直到这一点。代码编译正确,但是一旦我输入了我的决定并且计算机输入了它的决定,“赢家”就不正确了。
例如:
玩家选择摇滚
电脑选择剪刀
这是一个平局
我想也许我输入了一些我的 if 语句不正确,因为我选择的一些答案是正确的(关于谁是真正的赢家),而有些则没有。
但是在回到我的代码并(多次)检查它们之后,它们对我来说似乎是正确的......
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

int computer;
srand(time(NULL));

} // else if statement8 CLOSED
} // MAIN bracket CLOSED
同样,编码不完整。我还得补充一些东西。
另外我很抱歉,我还是编码新手。如果我对我的问题不够彻底或者我在代码页上添加了太多内容,请原谅我......我不知道要包含或排除哪些部分
解决方案
修复 if 语句的所有括号
例子
从:
if(player=='r' || player=='R' && computer==1){
至:
if((player=='r' || player=='R') && computer==1){
