Let’s say that you have two friends “Mike” and “Adam”. You want to make two biscuits for them and you want to gift them the biscuit.
Run the code and we will see that
both the biscuits output the same message
Mike this biscuit is a gift for you.
We want the second message to be for
Second message should have been
Adam this biscuit is a gift for you.
To solve this problem we need the name of the person to be a variable. In Ruby we can pass values to methods.
First let’s see how we solve this problem then we will discuss it.
We are removing the
eat method since that’s not important for now.
First let’s see how we are calling the method
# iniitally biscuit1.gift # now biscuit1.gift("Mike")
Now when we are calling the method
we are also passing the name of the person for whom the gift is.
Let’s see what has changed on the method side.
# initially def gift ... end # now def gift(name) ... end
Here we have declared a variable called
biscuit1.gift("Mike") is called then
name gets the value “Mike”.
biscuit2.gift("Adam") is called then
name gets the value “Adam”.
I know all this is confusing. We will go over these concepts again in the next lesson.
