Learn C Programming

By: Jeff Szuhay

Overview of this book

C is a powerful general-purpose programming language that is excellent for beginners to learn. This book will introduce you to computer programming and software development using C. If you're an experienced developer, this book will help you to become familiar with the C programming language. This C programming book takes you through basic programming concepts and shows you how to implement them in C. Throughout the book, you'll create and run programs that make use of one or more C concepts, such as program structure with functions, data types, and conditional statements. You'll also see how to use looping and iteration, arrays, pointers, and strings. As you make progress, you'll cover code documentation, testing and validation methods, basic input/output, and how to write complete programs in C. By the end of the book, you'll have developed basic programming skills in C, that you can apply to other programming languages and will develop a solid foundation for you to advance as a programmer.

Some more useful compiler options

Up until now, we have been compiling our programs with just the -o output_file option. Your compiler, whether gcc, clang, or icc, probably unbeknownst to you before this point, has a bewildering array of options.

If you are curious, type cc -help into your command shell and see what spews out. Tread lightly! If you do this, just understand thatyou will never need the vast majority of those options. Some of these options are for the compiler only; others are passed on to the linker only. They are there for both very specialized system software configurations and for the compiler and linker writers.

If you are using a Unix or Unix-like system, try man cc in the command shell to see a more reasonable list of options and their usage.

The most important of these options, and the one we will use from now on, is -std=c17 or -std=c11. The -std switch tells the compiler which version of the C standard to use. Some compilers default...
