C Language
The C
Programming language is used to write programs. Using this language we can send
instructions to the computer for achieving a particular task. C is one of such
high label language.
C was
developed by Dennis Ritchie at bell laboratory in USA in 1970-72. This language
is a combination of languages BCPL(Basic Combined Programming Language) and B
which were also developed by Bell.
Advantage of
C
Various advantage of C is:-
1)
C is powerful and flexible language.
2)
C is portable language.
3)
Using C we can create tables of constant data
with in the same file
4)
C program can be executed much faster than
the high label language
5)
We can create operating system using C .
Ex—windows, linux, unix, etc.
Disadvantage of C
1)
In C, there are very few instrinsic operations
and all heavy work is done through the library function call
2)
In C there is no mechanism for 3 type checking
Constants
Constant in C refer to fixed value that does not change
during execution of programs. If a variable is declared as should not try to
change its value.
Variable is used to represent.
Variable
1)
Primary variable-> integer,real,char etc
2)
Secondary variable-> Array, pointer,
structure etc
Rules of variable names:
i)
A variable name any combination alphabets,
digits, or underscores.
ii)
The first character in the variable name must be
an alphabet or underscores
iii)
No commas and blanks are allowed with in a variable
name
iv)
No special symbol or key words are use as
variable name
C key words
Key words are words whose meaning has already been explained
to the C compiler. The key words are also called “reserved word”
There are 32 key words are
available in C

Compiler:
A compiler converts the code written in programming language
into machine language
String:
A string constant is a one dimensional array of characters
terminated by a null (‘\0’).
Ex- char name [15];
String format-> %s
String scan-> gets
Clear the input buffer-> fflush(stdin)
Array:
An array is a collection of elements of a single data type store
in a memory location. It is a collection. It is a collection of element of the
same type that are referenced by a common name. Each element in an array can be referenced to be an array
name and index number.
An array is a way to group together a number of variables of
a single data type. Which have a single name followed by an index.
Element
Each variable stored in
an array called an array is called an element. The elements have an index. The
index of the first array element is zero(0).
Array declaration
1) Type of the array (int, float, char, etc)
2) Name of the array.
3)Number of Dimension.
4)Size of array (number of element).
Sintax:
Data type array name [size];
Int roll[500];
Arrays are two type-
1)
One dimension
2)
Multi dimension(two,three,four……….)
Functions
What is function?
A function is a self contained block of statement that
perform valid task of some kind. Every C program can be thought of as a
collection of different function.
There are basically two types of function in C.
1)
Library function
2)
User define function
What is library function?
Library function are
prewritten and precompiled by the compiler vendor and come along with
the compiler software as a library of function. It is not modified by the user.
Ex- printf(), scanf() etc
What is user define function?
The function defined by user for his/her requirement are
called user define function.
Return:
Pointer is a special type of variable. Which contain another
variable address. Pointer variable declared with ‘*’ sign.
Call by value:
In this method of function call the “value” of which of the
actual arguments in the calling function is copied in to the corresponding of
the called function. With this method, to change the mode to the formal
argument in the called function have no effect value of the actual argument of
the calling function.
Call by reference
In this method of function call the “address” of the actual
arguments in the calling function is copied into the formal argument of the
called function. With this method to change made to formal argument in the
called function have effect on the calling function.
