optional parameter in functions

[Junkone]

how do i make a parameter optional. if it is possible.
for eg. i want to do as follows

function myCall(a,b,c=somedefault)
...
end


myCall(a,b,c) or myCall(a,b)

Except for the fact that in ruby you define methods with "def" and
not "function", what you wrote above is perfectly valid ruby code
and works as intended.

You've got the basic idea. You just set the optional parameter to a
default value
Hello, Bob
=> nilHello, World
=> nil
