Conditional Operator in Ruby
The conditional operator in Ruby is a shorthand way of writing an if-else statement. It allows you to write a concise expression that evaluates a condition and returns one of two values based on the result of the condition.
The syntax of the conditional operator in Ruby is as follows:
condition ? value_if_true : value_if_false
Here's an explanation of each step involved in using the conditional operator:
- The condition is evaluated. It can be any expression that returns a boolean value (
true
orfalse
). - If the condition is
true
, the value specified before the:
is returned. - If the condition is
false
, the value specified after the:
is returned.
Let's consider an example to illustrate the usage of the conditional operator in Ruby:
age = 20
message = age >= 18 ? "You are an adult" : "You are not an adult"
puts message
In this example, the condition age >= 18
is evaluated. If the condition is true
(which it is in this case), the value "You are an adult"
is assigned to the variable message
. If the condition is false
, the value "You are not an adult"
is assigned to message
. Finally, the value of message
is printed, which in this case would be "You are an adult"
.
The conditional operator is a useful tool for writing concise and readable code when you have simple if-else conditions. However, it's important to use it judiciously and consider readability and maintainability when using it in more complex scenarios.
