你好，所以基本上我是大学新生，学习计算机科学课程，我正在努力学习自己（比其他人领先一步）

在这个程序中我的目标是制作一个响应式机器：带有2个或更多答案选项的问题，如果答案不在上下文中，则使用系统（“CLS”）然后重复问题（循环）。装饰：用于颜色的“系统颜色”，用于字母动画的“usleep”，用于字线之间的间隙的“sleep_for”

1.我如何修复while命令，它无法检测到我是否同时将两个条件都设置为“while（word！=”A“|| word！=”a“）;”如果有一种更简单的方法来逐字逐句，请告诉我。

Answer 1

错误> while(word!="A"|| word!="a");

修复> while(word!="A"&& word!="a");
