# Programming assignment C++

**Question description**

In this project, we want to write a program, that ask the user for three coefficients a2, a1, and a0, in order to solve any cubic polynomial equation of form: z^3 + a2z^2 + a1z + a0 = 0.

The formula is explained at: http://mathworld.wolfram.com/CubicFormula.html

First compute the intermediate variables Q, D, and D.

If D < 0, they are three solutions z1, z2, and z3. Compute and print out the three solutions

else compute the intermediate values S and T.

Now, if D equal to zero and S+T in=s not equal to zero, there are two solutions. Compute and print both solutions

else there is only one solution: z1

Submit your source file (.cpp). Any other file yields zero grade.
