Hello Lua_01

First, let's look at an introductory example:

-----------------------------------------------

-- file: '0525.lua'

-- desc: one ex

 

helpful_guys = {

    "----这是一个引导性的例子,从这里开始.----",

    "一月", "二月", "三月",

    "四月", "五月", "六月",

    "\n",

 

    "----第二段----",

    "星期一", "星期二", "星期三",

    "星期四", "星期五", "星期六",

    "\n"

}

 

for _,e in ipairs(helpful_guys) do

    print(e)

end

Runtime result:

 

Look familiar?  hehe, go on:

 

-- defines a factorial function

function fact (n)

    if n == 0 then

       return 1

    else

       return n * fact(n-1)

    end

end

 

print("enter a number:")

a = io.read("*number")      -- read a number

print(fact(a))

 

Runtime result:

>Exit code: 0
>lua -e "io.stdout:setvbuf 'no'" "0525.lua"
enter a number:
3
6
>Exit code: 0
