What does != mean?

What does != mean?

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

Answer: (A)

The not-equal-to operator checks whether two values are different. It returns true when they differ and false when they’re the same, which makes it handy in conditions to run code only if two values don’t match. For example, in a conditional like if (a != b) { … }, the block executes only when a and b are not equal. This is the opposite of the equality check, and it’s separate from relational comparisons like less-than or greater-than, which measure order rather than equality. A couple of simple examples: 5 != 3 is true, and 4 != 4 is false.
