The **conditional ternary operator** assigns a value to a variable based on some condition. This operator is used in place of the `if-else` statement. 

The operator first evaluates for a true or false value and then, depending upon the result of the evaluation, executes one of the two given statements​.

- The value of the condition determines which value is used.
- The value after the `?` is returned if the condition returns `true`.
- The value after the `:` is returned if the condition returns `false`.

The code below shows a simple `If else` condition testing code and its equivalent code using the ternary operator:​

marks = 65
if marks > 40
   puts "Pass!"
else
   puts "Fail!"
end

If-else

marks = 65
grade = marks > 40 ? "Pass!" : "Fail!"
puts grade

Ternary

# Multiple ternary operators

Multiple  `else if` statements can be used for variations of the same test case. The code below shows how these multiple variants can be implemented through both `else if` and ternary operators.​

marks = 85
if marks > 80
   puts "Distinction!"
elsif marks > 40
   puts "Pass!"
else
   puts "Fail!"
end

marks = 85
grade = marks >80 ? 'Distinction!' : marks > 40 ? 'Pass!' : 'Fail!';
puts grade

# Multiple operations
Multiple operations can be performed with a ternary operator. The commands must be separated with `;` (semicolons). The code below sets the value of the `grade` variable and then prints a message with the value if it fulfills the corresponding condition:



marks = 65
grade = ''; 
marks > 40 ? (grade ='Pass!'; puts "Welldone!")
  : (grade = 'Pass!'; puts "Better luck next time.");

puts grade
