c++ help please! much appreciated! need a .cpp and .hpp file that can successfully run through these tests, thank you very much! printed below to be able to copy/paste into a compiler

#include "catch/catch.hpp" #include "../matrix3d.hpp"

TEST_CASE ("Default Matrix") { Matrix3D m; CHECK(0 == m.GetValue(0, 0)); }

TEST_CASE ("Specified Matrix") { /* 1 0 2 1 2 0 1 0 0 */

Matrix3D m(1,0,2, 1,2,0, 1,0,0); CHECK(1 == m.GetValue(0, 0)); CHECK(2 == m.GetValue(0, 2)); }

TEST_CASE ("Determinant for default matrix") { Matrix3D m; CHECK(0 == m.Determinant()); }

TEST_CASE ("Determinant for specified matrix") { Matrix3D m(1,0,2, 1,2,0, 1,0,0); // https://www.wolframalpha.com/input/?i=%7B%7B1%2C0%2C2%7D%2C%7B1%2C2%2C0%7D%2C%7B1%2C0%2C0%7D%7D CHECK(-4 == m.Determinant());
