What is a virtual function? A virtual function is a member function which is declared within a base class, and that you expect to be redefined in derived classes. So what is a virtual function in C++? In C++, a virtual function is usually used to achieve runtime polymorphism, one of...

Now I’ll examine the assembly listing file of source2.c, which is much more interesting. The call to the cube function in sumOfCubes has been inlined. This in turn has enabled the compiler to perform significant optimizations on the loop (as you’ll see in the “Loop Optimizations” se...

In all IS-IS PDUs, the first eight bytes are public. The meaning and function of each field in a Hello PDU are described as follows: Intradomain Routing Protocol Discriminator: network layer protocol identifier. In IS-IS, the value of this field is always 0x83. Length Indicator: length ...
The Curiously Recurring Template Pattern (CRTP) is a form of compile-time polymorphism which allows you to extend types with common pieces of functionality without paying the runtime costs of virtual functions. This is sometimes referred to as mixins (this isn’t all the CRTP can be used for...
