Let’s look at the C++ code used to test the timing to walk through inheritance and virtual functions. The parent is the class PinOutputAbstract . It represents an output pin on an Arduino: ...

Write a C++ program to implement polymorphism by overloading an operator to add two objects of a class. Create an abstract class in C++ and implement it in a derived class. Explain the use of pure ...

I have read in several books (including a book on using QT toolkit) warning about using C++'s virtual function because of performance penalty.But they are quite vague on why this is so. Can ...

The program was from a final project in my C++ course that was meant to test knowledge of polymorphism and virtual functions. The function centers around the areas of a circle and the ares of a ...

The vast majority of nowadays remote code execution attacks target virtual function tables (vtables). Attackers hijack vtable pointers to change the control flow of a vulnerable program to their will, ...

Memory corruption bugs are one of the most critical vulnerabilities in software security, which can be exploited to overwrite virtual tables (vtables) or virtual table pointers (vfptrs) and finally ...
