Which symbol represents the logical AND operation?

• A. &&
• B. ||
• C. !
• D. =

Answer: (A)

In programming, the logical AND operation combines two boolean expressions and yields true only if both expressions are true. The symbol used for this operation in most languages is &&, which you read as “and” between the two conditions. For example, in a condition like (a > 0 && b > 0), the overall result is true only when both a > 0 and b > 0 are true. The other symbols correspond to different ideas: || stands for logical OR and becomes true if at least one side is true; ! negates a boolean value; = is used to assign a value (not to combine booleans). The essential idea is that && requires both parts to be true to produce a true result.
