Pointer are a fundamental part of C. If you cannot use pointers properly then you have basically lost all the power and flexibility that C allows. The secret to C is in its use of pointers.
Dynamic allocation is a pretty unique feature to C (amongst high level languages). It enables us to create data types and structures of any size and length to suit our programs need within the progra
We have introduced many applications and techniques that use pointers. We have introduced some advanced pointer issues already. This chapter brings together some topics we have briefly mentioned and
We have seen how pointers give us control over low level memory operations.
Many programs (e.g. systems type applications) must actually operate at a low level where individual bytes must be opera
This is a C Programming Tutorial for people who have a little experience with an interpreted programming language, such as Emacs Lisp or a GNU shell.
Before we embark on a brief tour of C’s basic syntax and structure we offer a brief history of C and consider the characteristics of the C language.
In this chapter we begin by outlining the basic processes you need to go through in order to compile your C (or C++) programs. We then proceed to formally describe the C compilation model and also ho
This Chapter deals with the various methods that C can control the flow of logic in a program. Apart from slight syntactic variation they are similar to other languages.
This chapter will look at C’s mechanisms for controlling looping and iteration. Even though some of these mechanisms may look familiar and indeed will operate in standard fashion most of the time. N
In principle arrays in C are similar to those found in other languages. As we shall shortly see arrays are defined slightly differently and there are many subtle differences due the close link betwee
