Ruby Return Value Of Assignment

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.

Ruby return value of assignment.

Ruby program that uses implicit return value def test x y this expression is evaluated and returned. 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. Def add two number number 2 end p add two 3 the last evaluated statement is the expression number 2. Result test 5 10 display the result.

Hashes enumerate their values in the order that the corresponding keys were inserted. False return value statements to shorten your if else structures. You are getting wiser and more confident with ruby. For more detail on ruby arrays go through ruby arrays.

That about covers methods. X 10 y end call test with two arguments. Here is the syntax. Ternary operator logic uses condition.

A trailing comma is ignored. True return value. Since almost everything is an object in ruby we can run the standard object id method on the variable to see its memory address. The value of just assignment 2 is going to be 5 because the assignment expression evaluates to 5 therefore that s what s returned.

A hash is a dictionary like collection of unique keys and their values. 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. In this case the return value for a object id is. 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.
