What is the ternary operator in Pearl?
Overview
In Pearl, we use ternary operators so we don't have to use the if-else statement. The operator makes the codes look nice and clean, which makes them easy to understand.
One of the most apparent important use of a ternary operator is that it replaces the use of the if-else state in a more clean, readable, and short form.
Syntax
cond ? val if true : val if false
Syntax
Parameters
cond: This is the code/expression whose output defines the value that is used.
- The value after the
?is returned if the condition returnstrue.
- The value after the
:is returned if the condition returnsfalse.
Example
print(1==0 ? 'right' : 'wrong',"\n");
Explanation
- Line 1: We use the ternary operator to check if
1is equal to0. This is definitelyfalse, and that's why thewrongmessage displays.
