我被困在我知道应该很容易解决的事情上,但我就是想不通我一直在谷歌搜索并浏览了我的文本(Gaddis C++ Intro,第 6 章)并尝试了一些事情 - 主要是移动循环,因为我认为我放错了;我也搜索了几个 C++ 论坛,我找到了一些例子,你问用户 j“你想继续/再玩一次吗”,但这不是我要做的,如果有,我会让它自动重启一个领带。它不断回到未在循环中定义/声明使用的变量——除了我不明白它们是如何不使用的。我正在使用 VS 2010。
这是代码。我很感激任何帮助。我觉得自己无法解决这个问题有点愚蠢。这是我的第一堂编程课,同时我也在学习 Visual Basic。这很有趣。
我得到的调试错误都是 cpuChoice 和 userChoice 的 C2065“未声明的标识符”。
