有一些愚蠢的语法，像花括号和分号，一开始是有点烦人的，因为你必须记住所有的这些要放到哪里。

There is some stupid syntax, like curly braces and semicolons, that initially is kind of annoying because you have to remember where all this goes.

youdao

开始/结束括号表示一个不带参数的函数。

The open/close parentheses denote a function that takes no parameters.

youdao

在HTML文档的样式部分中，输入类名、一个空格和一个前花括号，开始定义。

In the style section of an HTML document, type the name of the class, a space, and an opening curly bracket to begin the definition.

youdao

And so what I was hinting at earlier when you put semicolons in the wrong place, and then proceed to have curly braces around arbitrary lines of code, you're creating an even more local scope there, which is generally not the right intended behavior.

在之前我暗示了,当你把一个分号放在错误的地方时,然后开始用花括号,括上任意行的代码，你在那里创建了一个局部范围，那个不是故意的行为。

Well, for a thing called main which itself is a function but a function I wrote, a tool I am writing at the moment not like printf which someone else wrote long ago, I have to say where does main start, where does main end, and I do that by using these curly braces.

至于这个名曰main的函数,由我们自己写的函数，也是一个工具,只不过由我们自己编写，而不是像printf那样已经由前人写好了,我们必须要说明main在哪开始，在哪结束，这样我们就要用到大括号了。
