Initialize array of pointers c++
Webbför 2 dagar sedan · Consider these classes: class base { public: virtual ~base () = default; void Func () const {} }; class derived : public base { private: using base::Func; // makes base::Func inaccessible }; The "using" in class derived makes access to base::Func through a derived* impossible, but through a base* the function can still be accessed. WebbTo check if an array is symmetric or not, we need to compare the first half of the array with the reverse second half of array. For this, we are going to use the std::equal () function from STL. In this function, we will pass three arguments, Advertisements. A pointer, pointing to the start of array i.e. arr.
