Testing equality

ruby-talk

Hi.

When I try to test equality of two strings, for example:

if object1.string==object2.string then puts object1.string end

I get nothing printed even though two strings are equal.

Why ?

Thanks

The best way is to try the code using irb and post the results if you are still stuck.
Most likely, though, the objects you are comparing not really equal. Try printing out the values before you compare them.

I got it. One string from comparison is from gets function so it has 'enter' character added on the end.

Apparently those objects are not equal.

And when doing that p is preferred to puts because it will reveal any
additional whitespace that you would not see otherwise.

Kind regards
