String output for a polynomial

[DigitalDragon]

I'm currently working on an assignment involving classes and Polynomials and one of the assignments is to implement a function:

string str();

which will return a string representation of a polynomial in the form ax^2+bx+c. if a = 0, it will output bx+c, and so forth. I have a, b and c.

I'm not sure where to begin with this - stringbuf seems to be a way, but I have no clue how to use it or if it's even the correct way to go about this.

Use stringstream. It works like cout, just when you want to get the string call .str() method.
