C++ Codes

            

Some of the following codes are designed for Turbo C++. Therefore, you are advised to redesign them as per your requirement. For my students at Mehran University, IDE of Dev C++ or Code::Blocks is preferred to design following Source Codes useful for all learners studying subject of numerical methods with computer applications in their undergraduate courses. In addition to this, it is quite fruitful to see amazing use of C++ keywords (switch, case, break, and default) in order to combine various source codes in just one single file.
