Programmieren in C

Professional C course of the FernUniversität in Hagen

The C programming language is a high-level programming language. The use of C is not limited to specific fields of application. In particular, due to the possibility of programming close to the machine with high runtime efficiency, the C language was also successful in system programming.

The goal of the course is to provide a basic overview of the C programming language, taking into account both the 1978 draft of Kernighan / Ritchie and the ANSI-C standard.

Chapter 1 - Introduction to the C programming language

In the first chapter, in addition to the historical development, an overview of the basic features of the programming language C is given. It deals with the lexicon of the programming language and the structure of programs, generally referred to as functions in C.

Chapter 2 - Data Types and Storage Classes

Chapter 2 deals with programming language specifics such as data types, data type attributes, storage classes, scopes, and initialization of data objects.

Chapter 3 - Operators and Expressions

This chapter introduces the use of operators and the syntax of expressions. Of particular importance for daily practical programming is the final priority scheme of all operators.

Chapter 4 - Instructions

The syntax and application of the instructions in C, especially the control structures, e.g. conditional statements, loop statements, and selection statements are covered in this chapter.

Chapter 5 - Fields and Pointers

The closely related topic fields and pointers are treated. In particular, the address calculations and the processing of fields and pointers are dealt with here in detail.

Chapter 6 - Functions

This chapter discusses the overall complex of functions such as defining, declaring, and calling functions. Of particular importance are the methods of parameter passing in the function calls.

Chapter 7 - Input and Output Functions

The subject of this chapter are the principles of file processing. The focus is on the widespread format-controlled input and output.

Chapter 8 - The Macro Preprocessor

This chapter discusses the macro preprocessor with all its advanced capabilities according to the ANSI-C standard.

Chapter 9 - Structures and Associations

This chapter completes the course with sections on structures and associations.
