Array TypeError: can't convert Fixnum into String

Question

I am experimenting with arrays, and am reading the book \"Beginning Ruby on Rails\" by Steve Holzner. I made the program:

array = [\'Hello\', \'there\', 1, 2         


        

Answer 1

you are trying to add an integer(fixnum) and a string, which is something you can't do on ruby unless you explicitly cast the integer(fixnum) to a string. in your code array2[0]holds a string value "banannas" and array2[1] holds an integer(fixnum) value 1. so for your code too run correctly you need too cast the value in array2[1] to a string value.

you can change your code on line 9 to this:

puts array2[0] + " " + array2[1]._s
