actually this one, i have to use + full_name.to_s + to avoid the error i 
just found that strange. i mean i am using a string method the to_s 
should be implicit shouldnt it? i dont know.

irb(main):030:0> def name_length
irb(main):031:1>   p "what is your first name?"
irb(main):032:1>   first = gets.chomp
irb(main):033:1>   p "what is your last name?"
irb(main):034:1>   last = gets.chomp
irb(main):035:1>   full_length = first.length + last.length
irb(main):036:1>   p "your full name has: " + full_length + "characters"
irb(main):037:1> end
=> nil
irb(main):038:0> name_length
"what is your first name?"
