他们为什么用;结束Java / C ++中的语句 [英] Why they used ; to end statements in Java/C++

问题描述

他们不应该使用。结束声明。他们可以使用 - >来调用方法。这只是一个疏忽吗？或者这里有更深入的内容？

Should not they have used . to end a statement. They could use -> to call a method. Was this just a oversight? Or there is some deeper going on here?

推荐答案

Java选择分号的语法类似于C和C ++。

Java picked the semicolon to have a syntax similar to C and C++.

C ++选择它的语法类似于C语言。

C++ picked it to have a syntax similar to C.

我猜C选择了分号因为B，ALGOL和Pascal已经使用过它，并且没有理由不使用已经接受的约定。

And I would guess that C picked the semicolon because B, ALGOL and Pascal already used it, and there was no reason not to use an already accepted convention.
