Lua语法与C语言有些相似也不太一样，写了语句学一下 微笑

--begina = --[[explain]] "ha";print(a)if a == "ha" then print("if test passed")else print("if used wrong")endb,c=2,3print(b,c)b,c=c,bif b==3 and c==2 then print("swap test passed") print(b,c)else print("swap error")enddo b = 6 if b==6 then print("code block test passed") else print("code block test error") endenddo d=true; local e="haha"endif d==true and e==nil then print("local test passed")else print("local test error")endc = 2^3if c == 8 then print("squert test passed")else print("test error")enda = "string will be ".."connected"print(a)x = x or a --if not x then x = v endprint(x)print(type(asdf))c=3-1.2;print(c)d = [[怎么会 怎么会 你竟原谅了我?]]print(d)function test (w) print("the num is "..w) local add=w+1 return add;endb=test(5)print(add,b)t={ 100, [100] = "I'm the 100th element", fsy= { ['age']=22, sex = "male", --如果是字符串，可以去掉引号和括号 },--元素之间必须用，隔开 20, -- 相当于t[2]=20}print(t[0])print(t[1])print(t[100])print(t.fsy.age)print(t[2])g = { age = 3, add=function (s,n) s.age=s.age+n end}g:add(10) --相当于g.add(g,10)print(g.age)

运行的结果如下：
