<p>Go语言是一种静态类型、强类型的编程语言，它在变量声明和使用方面有着自己独特的规则和特点。以下是关于Go语言变量的详细介绍及相关代码示例。</p><p>变量声明</p><p>在Go语言中，变量声明使用关键字<span style="color: #ce9178;">"var"</span>。语法格式为：<span style="color: #569cd6;">var</span> 变量名 类型。变量名必须以字母或下划线开头，可以由字母、数字或下划线组成。例如：</p><pre class="brush:as3;toolbar:false">var age int var name string var flag bool</pre><p>还可以使用短变量声明的方式进行变量声明和初始化：</p><pre class="brush:as3;toolbar:false">age := 18 name := "Tom" flag := true</pre><p>变量类型</p><p>Go语言的基本数据类型有bool、<span style="color: #569cd6;">string</span>、<span style="color: #569cd6;">int</span>、float等。在Go语言中，变量类型可以在变量名之后指定，也可以通过编译器自动推导得出。例如：</p><pre class="brush:as3;toolbar:false">var age int var name string var flag bool a := 1 b := "Hello" c := true</pre><p>变量赋值</p><p>在Go语言中，变量赋值使用等号<span style="color: #ce9178;">"="</span>。例如：</p><pre class="brush:as3;toolbar:false">age := 18 name := "Tom" flag := true age = 20 name = "Jerry" flag = false</pre><p>多重赋值</p><p>在Go语言中，可以使用多重赋值的方式同时给多个变量赋值。例如：</p><pre class="brush:as3;toolbar:false">a, b := 1, 2 a, b = b, a</pre><p>常量声明</p><p>在Go语言中，常量使用关键字<span style="color: #ce9178;">"const"</span>进行声明。常量必须在声明时进行初始化，且初始化后不可更改。例如：</p><pre class="brush:as3;toolbar:false">const PI float64 = 3.1415926 const age int = 18 const name string = "Tom"</pre><p><br/></p>
