Is Carbon going to be a real replacement for C++? Let's find out.

True exact I. Qed. The first exercise: Get a root of the polynomial x**3 + 3*x**2 + 4*x + 2 0 using z3. Can you use z3 to show this is the only solution? Here we open up the reals. It is easy enough to confirm that the solution of x -1 is a zero using the [ring] tactic. Require Import Reals. Open Scope R_scope. Print Scope R_scope. Scope R_scope Delimiting key is R Bound to class R "r ²" : Rsqr r "x ^ y" : pow x y "x y" : Rge x y "x y" : Rgt x y "x y z" : and (Rle x y) (Rle...
