sir i am gurpreet . I found your site as a good soruce of programs . i have done MCA.. sir can i use your site to interact with other members..for the purpose of making concepts clear..this will help me as well as others. i want to share my programing skills with your students.
for chandni....
you can also write this to find greater no.
(m>n ? printf("m is greater"):printf("n is greater"));
hello gurpreet....
your concept is also right but we are following this pattern for writting programs in the college as i hav written in my program just to simplify things.
but thanks to you, for sharing this n please continue to discuss
the points like this in future.

DECLARATIONS IN C LANGUAGE
ANS
Informally, a variable (also called an object) is a place you can store a value. So that you can refer to it unambiguously, a variable needs a name. You can think of the variables in your program as a set of boxes or cubbyholes, each with a label giving its name; you might imagine that storing a value ``in'' a variable consists of writing the value on a slip of paper and placing it in the cubbyhole.
A declaration tells the compiler the name and type of a variable you'll be using in your program. In its simplest form, a declaration consists of the type, the name of the variable, and a terminating semicolon:
char c;
int i;
float f;
You can also declare several variables of the same type in one declaration, separating them with commas:
int i1, i2;
Later we'll see that declarations may also contain initializers, qualifiers and storage classes, and that we can declare arrays, functions, pointers, and other kinds of data structures.
The placement of declarations is significant. You can't place them just anywhere (i.e. they cannot be interspersed with the other statements in your program). They must either be placed at the beginning of a function, or at the beginning of a brace-enclosed block of statements (which we'll learn about in the next chapter), or outside of any function. Furthermore, the placement of a declaration, as well as its storage class, controls several things about its visibility and lifetime, as we'll see later.
You may wonder why variables must be declared before use. There are two reasons:
It makes things somewhat easier on the compiler; it knows right away what kind of storage to allocate and what code to emit to store and manipulate each variable; it doesn't have to try to intuit the programmer's intentions.
It forces a bit of useful discipline on the programmer: you cannot introduce variables willy-nilly; you must think about them enough to pick appropriate types for them. (The compiler's error messages to you, telling you that you apparently forgot to declare a variable, are as often helpful as they are a nuisance: they're helpful when they tell you that you misspelled a variable, or forgot to think about exactly how you were going to use it.)
Although there are a few places where declarations can be omitted (in which case the compiler will assume an implicit declaration), making use of these removes the advantages of reason 2 above, so I recommend always declaring everything explicitly.
Most of the time, I recommend writing one declaration per line. For the most part, the compiler doesn't care what order declarations are in. You can order the declarations alphabetically, or in the order that they're used, or to put related declarations next to each other. Collecting all variables of the same type together on one line essentially orders declarations by type, which isn't a very useful order (it's only slightly more useful than random order).
A declaration for a variable can also contain an initial value. This initializer consists of an equals sign and an expression, which is usually a single constant:
int i = 1;
int i1 = 10, i2 = 20;
________FINISH__________-
ARITHMETIC OPERATORS IN C LANGUAGE
ANS:
The basic operators for performing arithmetic are the same in many computer languages:
+ addition
- subtraction
* multiplication
/ division
% modulus (remainder)
The - operator can be used in two ways: to subtract two numbers (as in a - b), or to negate one number (as in -a + b or a + -b).
When applied to integers, the division operator / discards any remainder, so 1 / 2 is 0 and 7 / 4 is 1. But when either operand is a floating-point quantity (type float or double), the division operator yields a floating-point result, with a potentially nonzero fractional part. So 1 / 2.0 is 0.5, and 7.0 / 4.0 is 1.75.
The modulus operator % gives you the remainder when two integers are divided: 1 % 2 is 1; 7 % 4 is 3. (The modulus operator can only be applied to integers.)
An additional arithmetic operation you might be wondering about is exponentiation. Some languages have an exponentiation operator (typically ^ or **), but C doesn't. (To square or cube a number, just multiply it by itself.)
Multiplication, division, and modulus all have higher precedence than addition and subtraction. The term ``precedence'' refers to how ``tightly'' operators bind to their operands (that is, to the things they operate on). In mathematics, multiplication has higher precedence than addition, so 1 + 2 * 3 is 7, not 9. In other words, 1 + 2 * 3 is equivalent to 1 + (2 * 3). C is the same way.
All of these operators ``group'' from left to right, which means that when two or more of them have the same precedence and participate next to each other in an expression, the evaluation conceptually proceeds from left to right. For example, 1 - 2 - 3 is equivalent to (1 - 2) - 3 and gives -4, not +2. (``Grouping'' is sometimes called associativity, although the term is used somewhat differently in programming than it is in mathematics. Not all C operators group from left to right; a few group from right to left.)
Whenever the default precedence or associativity doesn't give you the grouping you want, you can always use explicit parentheses. For example, if you wanted to add 1 to 2 and then multiply the result by 3, you could write (1 + 2) * 3.
By the way, the word ``arithmetic'' as used in the title of this section is an adjective, not a noun, and it's pronounced differently than the noun: the accent is on the third syllable.

HOW TO DECLARE A VARIBLE IN C LANGUAGE:
how tWithin limits, you can give your variables and functions any names you want. These names (the formal term is ``identifiers'') consist of letters, numbers, and underscores. For our purposes, names must begin with a letter. Theoretically, names can be as long as you want, but extremely long ones get tedious to type after a while, and the compiler is not required to keep track of extremely long ones perfectly. (What this means is that if you were to name a variable, say, supercalafragalisticespialidocious, the compiler might get lazy and pretend that you'd named it supercalafragalisticespialidocio, such that if you later misspelled it supercalafragalisticespialidociouz, the compiler wouldn't catch your mistake. Nor would the compiler necessarily be able to tell the difference if for some perverse reason you deliberately declared a second variable named supercalafragalisticespialidociouz.)
The capitalization of names in C is significant: the variable names variable, Variable, and VARIABLE (as well as silly combinations like variAble) are all distinct.
A final restriction on names is that you may not use keywords (the words such as int and for which are part of the syntax of the language) as the names of variables or functions (or as identifiers of any kind).
FUNCTIONS IN C LANGUAGE:
Functions
C provides functions which are again similar most languages. One difference is that C regards main() as function. Also unlike some languages, such as Pascal, C does not have procedures -- it uses functions to service both requirements.
Let us remind ourselves of the form of a function:
returntype fn_name(1, parameterdef2,)
{
localvariables
functioncode
}
Let us look at an example to find the average of two integers:
float findaverage(float a, float b)
{ float average;
> average=(a+b)/2;
return(average);
}
We would call the function as follows:
main()
{ float a=5,b=15,result;
result=findaverage(a,b);
printf("average=%fn",result);
}
Note: The return statement passes the result back to the main program.
void functions
The void function provide a way of emulating PASCAL type procedures.
If you do not want to return a value you must use the return type void and miss out the return statement:
void squares()
{ int loop;
for (loop=1;loop<10;loop++);
printf("%dn",loop*loop);
}
main()
{ squares();
}
NOTE: We must have () even for no parameters unlike some languages.
PREPROCESSOR STATEMENTS
ANS:
The Preprocessor accepts source code as input and is responsible for
removing comments
interpreting special preprocessor directives denoted by #.
For example
#include -- includes contents of a named file. Files usually called header files. e.g
#include math.h -- standard library maths file.
#include stdio.h -- standard library I/O file
#define -- defines a symbolic name or constant. Macro substitution.
#define MAX_ARRAY_SIZE 100
