A heartwarming new video sees a dog teach a struggling baby how to crawl. Valerie Stevens-Scott from Atlanta, Georgia, filmed the family pet, Buddy, giving her seven-month-old daughter, Allie, an impromptu how-to session after he spotted her frustratingly waving her arms and legs around on the floor.
What is the Ternary Operator? The ternary operator is an operator that takes three arguments. The first argument is a comparison argument, the second is the result upon a true comparison, and the third is the result upon a false comparison. If it helps you can think of the operator as shortened way of writing an if-else statement.
In many programming languages, string concatenation is a binary infix operator. The + (plus) operator is often overloaded to denote concatenation for string arguments: Hello,  + World has the value Hello, World. In other languages there is a separate operator, particularly to specify implicit type conversion to string, as opposed to more complicated behavior for generic plus. Examples include . in Edinburgh IMP, Perl, and PHP, and & in Ada and Visual Basic. Other syntax exists, like || in PL/I and Oracle Database SQL.
