Which symbol represents the 'and' logical operator?

• A. ||
• B. &
• C. &&
• D. and

Answer: (C)

Conjunction in conditional logic means both conditions must be true for the overall result to be true. The standard symbol for this logical "and" in many programming languages is a double ampersand: &&. It expresses that both sides have to hold. The other symbols don’t fit the same role: || is the OR operator, which would be true if either side is true; a single & is often used for bitwise AND or not the typical boolean AND in many languages; and the word and is a keyword in some languages but not the symbol used for boolean conjunction. So the double ampersand best represents the logical and.
