Programming C work about polynomials
i have to do this work about polynomials, and i have to do some multiplications between two polynomials .
My problem is i have to put the formula of the polynomial after i multiplicate . and it has to be something like this :
" 1 + 2 x**2 + 3x**5"
I have to do some printf i guess, because it is not supposed to know the value of x and the values with 0 should not appear nor their x**n.

Just to let you know, C and C++ don't have a ** operator. The equivalent for this is the pow() function.

I take it you need to multiply the polynomials rather than evaluate them.

How are the coefficients entered?
What does the output need to look like?

Please show your programming effort, if by chance you can't make it work, and you'll get some advice.

Code:
              2      3
y(x) = 1 + 4 x  - 3 x

1+4x**2-3x**3

although the latter would paste functionally directly into python and many other languages.
