number squared in programming

Question

I know this is probably a very simple question but how would I do something like n² in a programming language?

Is it n * n? Or is there another way?

Answer 1

n * n is the easiest way.

For languages that support the exponentiation operator (** in this example), you can also do n ** 2

Otherwise you could use a Math library to call a function such as pow(n, 2) but that is probably overkill for simply squaring a number.
