The operator != stands for which relation?

• A. Greater than
• B. Less than
• C. Equal to
• D. Not equal to

Answer: (D)

Inequality checks whether two values are different. The symbol not equal to is read as "not equal to" and it yields true when the two values differ, and false when they are the same. For example, 5 not equal to 3 is true, whereas 4 not equal to 4 is false. This is different from greater than or less than, which compare order rather than equality. It’s also different from the equals operator, which checks if values are the same. Some languages use variations like a strict not equal (for example, !== in JavaScript) to differentiate both value and type, but the core idea remains: not equal to means the values do not match.
