Hi All,

Here is my code snippet:-  
my\_array = [1,2,3]  
puts my\_array.each {}

or

my\_array = [1,2,3]  
my\_array.each {|x| puts x}

O/p:-  
1  
2  
3

I want to know how the array.each works. How the compiler interprets and  
prints.

Thanks and regards,  
Neela.

[http://www.ruby-doc.org/core/classes/SOAP/RPC/SOAPMethodResponse.html#M006286](http://www.ruby-doc.org/core/classes/SOAP/RPC/SOAPMethodResponse.html#M006286)  
each will iterate over each element in the array and then yield to a  
supplied block with a single variable, the item in the array.  
If you have a look at the C code, you’ll see a familiar looking for  
loop with calls to yield.

For a better understanding, you need to do some further reading on  
blocks in ruby.
