Answer 1

C# 和 Java 的语法都受到 C 的启发，并继承了 C 语法的所有怪癖。关于为什么 Go has a different syntax 有一篇很好的文章:

Go syntax

Languages outside the C family usually use a distinct type syntax in declarations. Although it's a separate point, the name usually comes first, often followed by a colon. Thus our examples above become something like (in a fictional but illustrative language)

x: int
p: pointer to int
a: array[3] of int

These declarations are clear, if verbose - you just read them left to right. Go takes its cue from here, but in the interests of brevity it drops the colon and removes some of the keywords:

x int
p *int
a [3]int

There is no direct correspondence between the look of [3]int and how to use a in an expression. (We'll come back to pointers in the next section.) You gain clarity at the cost of a separate syntax.
