Ruby Return Value Of Assignment

The value of just assignment 2 is going to be 5 because the assignment expression evaluates to 5 therefore that s what s returned.

Ruby return value of assignment.

False return value statements to shorten your if else structures. That about covers methods. For more detail on ruby arrays go through ruby arrays. 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. 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. Result test 5 10 display the result. 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.

You are getting wiser and more confident with ruby. 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. 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. Once the is assigned a value the conditional assignment operator cannot be over written.

A hash is a dictionary like collection of unique keys and their values. A trailing comma is ignored. 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. 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.

X 10 y end call test with two arguments. Ternary operator logic uses condition. In this case the return value for a object id is. Def add two number number 2 end p add two 3 the last evaluated statement is the expression number 2.
