What is polynomial in c language?

Answer 1

A polynomial is a mathematical equation in the form ...

f(x) = Ax0 + Bx1 + Cx2 + Dx3 ... etc.

Often, the ordering of the terms is the other way around, but I used this order to segue into the discussion of computer representation.

What you need, are the coefficients, A, B, C, D, etc. in an array. Most often, one would create an array of double, and place the coefficients into the array.

double x[4] = {A, B, C, D};

This way, x[0] = A, x[1] = B, etc. and you could write code to manipulate the polynomial in various ways.
