Sometimes friends ask me for help with C++ problems. I start therefor here a small collection of sample files for C++. The files are not very ambitious and should be compilable with any C++/Rev11 compiler.
Some STL samples dealing with containers may be found here.
This C++ sample file explains how derivation(inheritance) works. It also shows the use of classes, class instances and pointers to class instances. A basic knowledge about pointers in Standard C is needed. Virtual functions are also illustrated.
In contrast to other programming languages like D C++ does not implement complex numbers in the language but in the STL library. The class complex is a templated class, i.e. it must be specified as complex<double> or complex<float>.
This C++ sample file shows how complex numbers can be handled in C++. Depending on the age of you compiler you have to play with the compile-time option "-std=". See the source code for comments. Some compilers do not follow completely the last conventions for complex numbers. Depending on the compiler you also have to play with naming conventions.
DLLs correspond under Windows (more or less) to shared libraries in other operating systems. Here are two programs (sources) written in standard C++ under Windows 32 Bit:
