C++ function that allows arbitrary class input -

right have class has method f:

class a{ public:     double f(double x){return 0.0;}; };

and have class b method f:

class b{ public:     double f(double x){return 0.0;}; };

i function myfun take in either class or class b without having overload function:

double myfun(a a){     return a.f(1.0); } double myfun(b b){     return b.f(1.0); }

i don't want overload function because have 3 or more different classes method f(). there way this?

use simple template function:

template<typename t> double myfun(t t) {     return t.f(1.0); }

and call like:

a a; myfun(a);  b b; myfun(b);

And
