Ternary operator logic uses condition.

Ruby return value of assignment.

X 10 y end call test with two arguments. Since almost everything is an object in ruby we can run the standard object id method on the variable to see its memory address. When return isn t explicitly called within a method then ruby returns the value of the last executed instruction in the method in the implicit return method as if true is always evaluated as true. You are getting wiser and more confident with ruby.

Once the is assigned a value the conditional assignment operator cannot be over written. False return value statements to shorten your if else structures. A trailing comma is ignored. In this case the return value for a object id is.

True return value. The value of just assignment 2 is going to be 5 because the assignment expression evaluates to 5 therefore that s what s returned. Since in our example number is assigned 3 this expression returns the number 5 and that is why the value returned by our method also is 5. Hashes enumerate their values in the order that the corresponding keys were inserted.

Ruby program that uses implicit return value def test x y this expression is evaluated and returned. A hash is a dictionary like collection of unique keys and their values. Also called associative arrays they are similar to arrays but where an array uses integers as its index a hash allows you to use any object type. A literal ruby hash is created by placing a list of key value pairs between braces with either a comma or the sequence between the key and the value.

Here is the syntax. I see from the example that the conditional assignment operator can change an empty variable in ruby to a specific value say if a method where expressed within a block code. It first evaluates an expression for a true or false value and then execute one of the two given statements depending upon the result of the evaluation. Result test 5 10 display the result.
