Introduction
C++ is a computer programming language, and as from one perspective, a computer program language is a sequence of instruction fed into a computer that dictate to the computer what to do. These instructions are executed through the flow of electrical impulses that affects the computer’s memory through interaction with the input and output devices. There are different types of computer programs playing different roles; one program might let a computer perform the role as a financial calculator, while another computer program could transform the computer into a worthy chess opponent. In the mid-1980s, Bjarne Stroustrup of AT and T Bell Labs developed the C++ programming language. C++ is an extension of the previously developed C programming language by AT and T Labs in the early 1970s. Originally, AT and T developed the C programing language to write UNIX operating systems, system-level software, and embedded system development. Initially, following after the development of the C++ programming language, it provided object-oriented programming features, and later on, generic programming capacities were added. The C++ programming language is useful in both commercial and industrial software development. C++ is a powerful programming language used for developing complex engineering, sciences, and business systems. Some common software written in C++ include Adobe Creative Suites, macOS, Microsoft Office, Microsoft Windows 8, and so on. The C++ programming language is complex itself so that it can meet up with the needs of commercial software development. Experienced software developers can accomplish great things with C++, but beginners may have a difficult time with it because it is closer to machine language than human language. We’re keen on understanding in this book, and so, to fully understand everything you need to know about C++ programing language, there are some development tools you need to acquit yourself to how they work.
This book is not aimed to cover all facets of the programming language, but to guide you on all, you ought to know about the C++ programming language. Despite the plethora of things you need to know about C++, this book will bring as much of it into ten concise chapters letting you learn all you need to know about C++ from A-Z.
Chapter 1 Writing a C++ Program
C++ has a particular structure of writing them. The syntax of the code much be correct. If not, the compiler would give an error message, and it would not be executable. In this chapter, we shall be introducing C++ with simple executable examples you can try. Most C++ codes are executable in a lot of other programming languages like C, Ada, C#, and Java but with a slightly different syntax. The General Structure of a Simple C++ Code Below is a one of the simplest C++ code that does something: #include int main() { std::cout
