问题集锦（7）
出现这个错误的原因在于：你使用了没有事先声明的函数。
void funcA(void)
int i = 0;
i = funcB();
int funcB(void)
在上面的例子中，funcA调用funcB时，就会出现这个报错。
解决方法：
先声明funcB，或者把funcB的实现放在funcA前面：
int funcB(void)
void funcA(void)
int i = 0;
i = funcB();
当然，也可能别的原因造成此问题。我遇到的是这种而已。

With the range modifier specified after the parameter list, any time DeAmperfyAll() is called with a range such as
在参数列表之后指定了 range 修饰符后，使用如下范围调用 DeAmperfyAll() 时
If you intend it to apply to just one noun, place that one noun at the end of the list and the modifier directly in front of it.
如果只修饰一个名词，那就在该名词的前面加上修饰语并将它们一起放的这组名词的最后。
That means that they should include the abstract keyword, optionally a visibility modifier, the function keyword, and an optional list of arguments in parentheses.
这意味着，抽象方法应包括 abstract 关键字、可选的可见度修改符、function 关键字，以及圆括号内可选的参数列表。

Command line

The Nextstep display is opened

;; startup.el will then examine startup files, and eventually call the hooks
