What does != mean in coding?

 In programming, "!=" is a comparison operator that represents "not equal to." It compares two values or expressions and returns true if they are not equal and false if they are equal. It is typically used in conditional statements and loops to determine whether two values are not equal.

For example, in many programming languages, you may encounter something like:

In this case, the output would be "x is not equal to y" because the values of x and y do not match.
