& Operator

Syntax

<expression1> & <expression2> <expression1> && <expression2>

Description

The ampersand (&) operator is a text concatenation symbol; it joins the expressions to its left and right to form a single expression. When the ampersand is used singly, the expressions are concatenated without any intervening characters. When a double ampersand (&&) is used, the expressions are joined with a single intervening space.
