Question

which comparison operator checks if two values are not equal?

○ !=

○ =!

○ ==

○ <>

Explanation:

In programming (especially languages like Python, Java, etc.), the != operator is used to check if two values are not equal. The =! is not a valid comparison operator syntax. The == operator checks for equality (not inequality). The <> operator is an older or less - common way (in some legacy languages like Visual Basic) but != is the standard and more widely used operator for "not equal" in many modern programming languages.

Answer:

A. !=
