Is that correct? Pointers or references are required for dynamically bound virtual functions.

How do function objects enable functional compositions, aiding in more readable and maintainable code?

Write a line of code that dynamically allocates memory space for an array of 20 structures of type ProductRegistration and assigns a pointer to the allocated memory to an appropriately-typed variable which you can name anything you like. You may assume that any required header files required by your answer have already been #include-ed.

use Advanced C++ techniques, containers and features to refactor the C/C++ algorithm.  The purpose is toreplace appropriate declarations and code segments with Advanced C++ declarations and code. * Replace all arrays with appropriate STL containers. * Use STL algorithms to REPLACE existing logic where appropriate. * Use smart and move pointers where pointers are needed.  * Use lambda expressions where appropriate. * Use C++ style casting when needed. * Look for opportunities where tuples could be used. * The code listing is in C and C++. If there are logic or syntax problems, please fix. #define BIND(A,L,H) ((L)<(A)?(A)<(H)?(A):(H):(L)) char  dih[50],dah[50],medium[30],word[30],*dd[2] = {dih,dah};const char  *ascii = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.,?'!/()&:;=+-_\"$@",  *itu[] =…
