These days computers have become ubiquitous in almost all areas of education, be it science, engineering, arts or any other. Particularly biology and other natural science students often have to struggle with enormous data related to the field applications of scientific information. And computational technology becomes much more important when multiple factors have to be considered, compromised or contained in the field of environmental management. Primarily, C language is used in the field of academics. In this book the authors have provided a simple and direct approach to the practical utilization of C programming for Environmental Management degree course and other natural science and technology students. The treatment of the subject is very simple and user-friendly so that anyone not familiar with C language but having basic acquaintance with computers can also use it and be benefited.
