Scalar Data Types,tively complex objects instead of the more mundane objects that the computer manipulates at its lowest level. You can deal with integers, characters, and floating-point numbers, all of which are familiar entities. At the bit and byte level, the computer may not understand these concepts. It is up to

Control Flow,n which they appeared without any branching or repetition. Most programming problems are not so simple. In fact, the great power of programming languages stems from their ability to instruct the computer to perform the same task repeatedly, or to perform a different task if parameters change. In hig

For this process to work, there must be a mechanism to ensure that variables declared by one programmer don’t conflict with unrelated variables of the same name declare

The C Preprocessor,vious chapters, we introduced two preprocessor directives—the . command for naming a constant and the . command for including additional source files. This chapter discusses both of these directives in greater detail and also describes other preprocessor directives that have not been mentioned yet.
