hi folks

i am damned new to Ruby can you help out:

the following ruby code - what does it print out?

PHP Code:



puts ((11000.to_s * 2).to_i/2)

Well the simple answer would be just run it and see

The tips would be:

to_s will turn the number into a string where by * will now return 2 lots of the string concatenated together

to_i turns the string above back into an integer

as the int will end in 0 it will be evenly divisible by 2 so you should end up with a whole number
