The first time we call it, with a single argument,igets 1. Then the function returnst[1]followed by all results fromunpack(t, 2), which in turn returnst[2]followed by all results fromunpack(t, 3), and so on, un
PS:在接收char的时候,会进行默认参数提升,变成int,所以需要以int型来接收char,同样,float也需要以double来接收,否则会出现编译错误。 E:\Clion\shiyan1\main.c: In function 'simple_printf': E:\Clion\shiyan1\main.c:36:34: warning: 'char' is promoted to 'int' when passed through '...' int c ...
例子 function func() print("this is a function") end t = {name = "table"} print(tostring(123)) --> 123 print(tostring("abc")) --> abc print(tostring(func)) --> function: 0x7f86348013b0 print(tostring(t)) --> table: 0x7f86348013e0 type (v) 返回 v 的类型,类型以字符串形式...
Lua 中有 8 个基本类型分别为:nil、boolean、number、string、userdata、function、thread 和 table。 局部变量: local b = 5,全局不需要 函数: 格式:function … end,可多返回值,变参... functionfoo() c =5 returnc end select(‘#’, …) 返回可变参数的长度。 select(n, …) 用于返回从起点 n 开...

type checking: function argument types and return types are checked against the specification, and raise an error if some don't match This is a light-weight library forLua5.1 (includingLuaJIT), 5.2, 5.3 and 5.4 written in pure Lua.
