proc in ruby

proc.rb

# In Ruby, a Proc is an object that represents a block of code that can be stored in a variable.
# It's a way to create an anonymous function or code block that can be assigned to a variable and passed around in your program.
# Procs are instances of the Proc class.
# Here's a basic example of using a Proc:

full_name = Proc.new{ |first, last| first + " " + last}

p full_name["Mashiro", "Moritaka"]  # we can call proc using [], using the bracket followed by the arguments
p full_name.call("Azuki", "Miho")  # we can also call proc using call method


add = Proc.new do |x, y|
  x + y
end

def do_operation (a, b, operation)
  operation.call(a,b)
end

p do_operation(1,2,add)
