通过Lua语言支持其他运算符包括串联和长度。
例子
试试下面的例子就明白了在Lua编程语言提供的其他运算符：
复制代码 代码如下:
a = "Hello "
b = "World"
print("Concatenation of string a with b is ", a..b )
print("Length of b is ",#b )
print("Length of b is ",#"Test" )
当建立并执行上面的程序它会产生以下结果：
复制代码 代码如下:
Concatenation of string a with b is Hello World
Length of b is 5
Length of b is 4
Length of b is 5
Length of b is 4
