This source code enables you to plot the solutions to scientific and engineering problems. The Visual C++ programming environment was chosen for realization of numerical computation techniques. Visual C++ includes many advanced features that make it especially suitable for scientific and engineering computations. Visual C++ is also widely used; there is a wealth of information available on how to program with it. Many of the features of Visual C++ enable you to write computer programs that can perform useful numerical computations. It includes an extensive set of mathematical functions. You may define classes of data together with methods to perform abstract operations such as vector and matrix arithmetic. A new project can be set up in the Visual C++ 6.0 environment using the following steps: (1) Select New from File menu. (2) In the New dialog box select "Win32 Application" and enter a project name. Then press the "Ok" button. (3) In the Win32 Application dialog box select "A simple Win32 Application" then press the "Finish" button. Press "Ok" in the New Project Information dialog box. (4) Open the *.cpp file for entry of the program. (We do not edit StdAfx.h or StdAfx.cpp; VC++ requires these files.) Enter, or copy, the following code into the empty application source file created using the process above. Here, the plotter class files are stored in a common directory so that they can be re-used for several plotting programs. (5) You must add the plotter source file plotter.cpp to the Visual C++ project in order for the program to compile and link successfully.
