Hash index value returns the key for the given value in hash nil if no matching value is found.

Ruby case statement return value.

With an if statement you can check if something is true. This returned value will be the value of the last statement. A much easier way to handle such situations is to use the ruby case statement the syntax for which is defined as follows. The return statement in ruby is used to return one or more values.

For the tests in these control expressions. A case statement will always return a single object just like a method call. Result case value when match1 then result1 when match2 then result2 when match3 then result3 when match4 then result4. Usr bin ruby for i in 0 5 puts value of local variable is i end here we have defined the range 0 5.

Hash indexes keys returns a new array consisting of values for the given key s. Ruby case ranges. For example def test i 100 j 10 k 0 end this method when called will return the last declared variable k. This will produce the following result.

Case capacity when 0 you ran out of gas. All the expressions described here return a value. Will insert the default value for keys that are not found. Every method in ruby returns a value by default.

So you can safely wrap a case statement in a method call and ruby will have no problems with it. But when you want to check for the opposite not true false. This method is deprecated. The statement for i in 0 5 will allow i to take values in the range from 0 to 5 including 5.

Return values from methods. Nil and false are false values. Things are no different when it comes to case statements. Else code end compares the expression specified by case and that specified by when using the operator and executes the code of the when clause that matches.

Hash has value value tests whether hash contains the given value. Let s see an example where we want to print some message depending on what range a value falls in. For example the above version of the case statement ca be re written like this. Here we have explained if expression ternary if unless expression modifier if and unless and case expression.

This can quickly become cumbersome however when a need arises to evaluate a large number of conditions. Notice that we use two equal symbols to mean equality. True and any other object are true values. The case statement is more flexible than it might appear at first sight.
