c++ Making a code that displays equations and keep getting the “expression must have integral or unscoped enum type” error

by

The issue is related to the modulo operator which expects a binary expression of two integers.

I’d suggest reading up a little on the rules of modulo and finding a way to adjust your code. Here is an answer about this and a suggestion how to go about fixing this error.

Why does modulus division (%) only work with integers?
