How to pass derived object in function as base object in C++ [closed]

Answer 1

You do realize that this

static void method1(equation eq, double dt);

is expecting a object of equation instead of pointer to eq

so if you just change this method to

static void method1(equation* eq, double dt);

the following should work as is.

equationSolver::method1(this, dt); // i am getting error here...

because simpleMotion IS_A equation
