Chapter 2. The Foundation of C

Here, we present the lexical syntax of C. An overview of C keywords is given. In this chapter, you shall have a look at the data types available in C. Presenting variables and constants, we delineate naming conventions for variables and modes of representing constant values along with functions, which are the basic building blocks of a C program. After getting our first look at two standard library functions for input and output, we move on to writing our first C programs using the techniques we discussed. At the end of this chapter, you will also be learning about the scope of variables in conjunction with the different types of storage classes and their usage. For starters, let us look at the memory of a typical ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
