在中使用的函数的开头声明变量。在那之后留下一排空的。在使用它们的值之前，也不要忘记在某个地方初始化它们，否则您只能得到垃圾

关于警告：

必须注意使用运算符的优先级。此外，&&和| |都是二进制运算符，因此它们都有两个参数。这就是为什么你必须加括号。可能像：

while(answer != 1 && (answer != 0 || status == 0))

---

那么声明这些变量呢？代码中有明显的语法错误。您似乎在使用函数参数作为局部变量。只需将answer声明为局部变量，并将其从参数列表中删除。

while(answer != 1 && (answer != 0 || status == 0))
