Overview

In this book the C++ is used as base language. Generally speaking there is a wide range of programming languages, from the old FORTRAN to the modern object-oriented C++, Java and a new language C#. Many books have written about the suitability of each language on each application. Besides often the choice of language is determined by the taste of the programmer. If you do not have a very large task, which one has to calculate with the maximal speed, there is nothing better than the fast FORTRAN [Press et al., 1992]. However we often meet the situation when one plans to develop the code and modernize it further, when the code occupies many thousand lines, and when both the logic of calculation and the expected result are not clear even for the developer. In these cases it is recommended to choose one of the object-oriented languages. In such languages an author has the opportunity to construct and develop the logic of the program in a close conformity with the physics of the problem. The code can be naturally shared into the separate parts (classes) which are independent of one another, reflecting the independence of the objects of the real world. Each part (object) can have a complicated internal structure. Furthermore such objects begin to interact by a logical and hereditary way. As a result the depth of the real problem can be achieved. The possibilities of various levels of access are available in the...
