The aim of this book is to analyze the construction machinery applications in tunneling operations and to calculate them in a shorter time with more precise results by coding in C++ programming language. In the competitive global market, the use of programming languages has become widespread with the developing computer technologies. C++ programming language, which is increasingly used in almost all engineering applications, has become more popular. Considering that the tunneling industry has been developed rapidly in recent years, it will be very useful for engineers and sector employees to make the calculations in this book and used in tunneling processes using the C++ programming language. This book, which shows how the C++ programming language is used in tunneling applications, will also be very useful for mining and civil engineering students. I hope that this book will be a pioneer for anyone working on programming in tunneling sector.
