An operator able to check whether two values are not equal is coded as:

Question

Options

• A!~
• B!=
• C=/=
• Dnot ==

• A
  4% (1)
• B
  86% (24)
• C
  7% (2)
• D
  4% (1)

Explanation

!= is the standard "not equal to" operator in most major programming languages including Python, JavaScript, Java, C, and C++. It evaluates to true when the two operands have different values, making it the direct complement of the equality operator ==.

Why the distractors are wrong:

• A (!~) is not a standard equality operator; ~ is a bitwise NOT or regex match operator in some languages, so this combination doesn't test equality.
• C (=/=) is not valid syntax in any mainstream programming language - it's simply not a recognized operator.
• D (not ==) - while not is a logical keyword in Python, not == is not an operator; you'd write != or use not (a == b) as an expression, not a standalone operator symbol.

Memory tip: Think of != as "not equals" - the ! character in programming conventionally means "not" (as in !true = false), so != literally reads as "not equal." If you remember == means "equals," just slap a ! in front to negate it.
