IntroductionSome time ago, we developed a set of printer software for our customers and made some research on calling printers in C. --------------------------------------------- Problem. NET Framework 1.1 provides us with a printersettings class to

Function call stack implementation. It can be used to implement a simple script interpreter. Statement: # Pragma once Const int buffersize = 1024; Const int growfactor = 2;   // This stack is used as call stack. Class tstack { PRIVATE: Size_t size;

In the previous article, we discussed the vector declaration. Next, you will see the vector interface and implementation. Class vector { Public: ... Iterator begin () {return start;} // return the beginning of vetorConst_iterator begin () const

Union provides a way to circumvent the type system of C and allow multiple types to reference an object. The syntax of Joint Declaration is the same as that of struct, but the semantics is quite different. Instead of referencing different memory
