Today, we will learn and use methods and return statement in our Program. Programming in Lua is more like Programming in C. If you are familiar with C then Lua is pretty easy to learn.
function IsEven (n) if n%2 == 0 then return "Even" else return "Odd" end end print("Enter a Number: ") a=io.read("*number") print("Number ",a,"is ",IsEven(a))
In the above program, we have created a method
IsEven(...), which takes a number as input and identifies if it is Even or Odd and returns a string which is printed as output to the console. Also, if you notice, we have used
a=io.read(...), this allows us to take an input from the user and read it using system io stream and assigns it to the
variable a for us to make use of.
The next program that we will learn will contain more code and will be a little more extensive. Stay tuned for that.
