Functions

FUNCTIONS
C enables its programmers to break up a program into segments commonly known as functions, each of which can be written more or less independently of the others. Every function in the program is supposed to perform a well-defined task. Therefore, the program code of one function 
is completely insulated from the other functions.
Every function interfaces to the outside world in terms of how information is transferred to it and how results generated by the function are transmitted back from it. This interface is basically specified by the function name. For example, look 
at below figure which explains how the main() function calls another function to perform a well-defined task.
Fig: main() calls func1()
In the figure, we can see that main() calls a function named func1(). Therefore, main() is known as the calling function and func1() is known as the called function. The moment the compiler 
encounters a function call, the control jumps to the statements that are a part of the called function. 
After the called function is executed, the control is returned to the calling program.
The main() function can call as many functions as it wants and as many times as it wants. For example, a function call placed within a for loop, while loop, or do–while loop may call the same function multiple times till the condition holds true.
Not only main(), any function can call any other function. For example, look at below figure which shows one function calling another, and the other function in turn calling some other function.
Fig : function calling another function

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. Rather, the execution o...

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...

HEAT AND THERMODYNAMICS

Heat: * Temperature is the thermal state of the body, that chooses the direction of flow of heat.  * “Heat is a form of energy transfer between two systems or a system and its surroundings due to temperature difference between them.  Specific heat capacity  * Specific heat capacity of a substance is determined as the quantity of heat required to raise the temperature of 1 kg of the substance through 1K. Its unit is J kg^–1K^–1. * The specific heat capacity of water is the highest for any substance, 4180 J/kg K. It is 30 times the specific heat capacity  of mercury which is about 140J/kg K.  Specific Latent Heat  Specific Latent Heat of fusion of any substance is the quantity of heat energy needed to melt one kilogram of a substance without change in temperature. The symbol used is L. The unit for specific  latent heat is Joule/kilogram or J/kg  The Gas Laws  * Boyle’s Law  “Temperature remaining constant, the pressure of a given mass of ...
