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 Adam.
The 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.
First, let's see how we are
calling the method gift:
Now, when we are calling
the method gift, then
we are also passing the name
of the person to whom the gift belongs.
Let's see what has
changed on the method side.
Here we have declared a variable called name.
When biscuit1.gift("Mike") is called then
name gets the value Mike.
Similarly, when biscuit2.gift("Adam")
is called then
name gets the value Adam.
We know all this is confusing.
We will go over these concepts
again in the next lesson.
