Example #1 :

# Ruby code for Hash.to_proc() method

# declaring Hash value
a = {a:100, b:200}

# declaring Hash value
b = {a:100, c:300, b:200}

# declaring Hash value
c = {a:100}


# to_proc Value
puts "Hash a to_proc form : #{a.to_proc()}\n\n"

puts "Hash b to_proc form : #{b.to_proc()}\n\n"

puts "Hash c to_proc form : #{c.to_proc()}\n\n"

Output :

Hash a to_proc form : #

Hash b to_proc form : #

Hash c to_proc form : #

Example #2 :

# Ruby code for Hash.to_proc() method

# declaring Hash value
a = { "a" => 100, "b" => 200 }

# declaring Hash value
b = {"a" => 100}

# declaring Hash value
c = {"a" => 100, "c" => 300, "b" => 200}

# to_proc Value
puts "Hash a to_proc form : #{a.to_proc()}\n\n"

puts "Hash b to_proc form : #{b.to_proc()}\n\n"

puts "Hash c to_proc form : #{c.to_proc()}\n\n"
