Introduction to C Programs

INTRODUCTION The programming language ‘C’ was developed by Dennis Ritchie in the early 1970s at Bell Laboratories. Although C was first developed for writing system software, today it has become such a famous language that a various of software programs are written using this language. The main advantage of using C for programming is that it can be easily used on different types of computers. Many other programming languages such as C++ and Java are also based on C which means that you will be able to learn them easily in the future. Today, C is mostly used with the UNIX operating system. Structure of a C program A C program contains one or more functions, where a function is defined as a group of statements that perform a well-defined task.The program defines the structure of a C program. The statements in a function are written in a logical series to perform a particular task. The most important function is the main() function and is a part of every C program.

Performance

Performance ( Optional ) * The I/O system is a main factor in overall system performance, and can place heavy loads on other main components of the system ( interrupt handling, process switching, bus contention, memory access and CPU load for device drivers just to name a few. ) * Interrupt handling can be relatively costly ( slow ), which causes programmed I/O to be faster than interrupt driven I/O when the time spent busy waiting is not excessive. * Network traffic can also loads a heavy load on the system. Consider for example the sequence of events that occur when a single character is typed in a telnet session, as shown in figure( And the fact that a similar group of events must happen in reverse to echo back the character that was typed. ) Sun uses in-kernel threads for the telnet daemon, improving the supportable number of simultaneous telnet sessions from the hundreds to the thousands.   fig: Intercomputer communications. * Rather systems use front-end processor...
