Introduction to the C programming Language

 

Introduction:-

±  C is a general-purpose high-level language
±  Father of C – Dennis Ritchie
±  Originally developed for the UNIX operating system
±  Implemented on the Digital Equipment Corporation, PDP-11 computer in 1972
±  The UNIX operating system and all UNIX applications are written in the C language


 C has now become a widely used professional language for various reasons:
±   Easy to learn
±   Structured language
±   It produces efficient programs
±   It can handle low-level activities
±   It can be compiled on a variety of computers

Why we use C?

±  C was initially used for system development work, in particular the programs that make-up the operating system
±  C was adopted as a system development language because it produces code that runs nearly as fast as code written in assembly language.

±  Some examples of the use of C might be:

°   Operating Systems
°   Language Compilers 
°   Assemblers
°   Text Editors
°   Network Drivers
°   Data Bases
°   Language Interpreters
°   Utilities 

Function of C:-

±  C is a case sensitive programming language. It means in C printf and Printf will have different meanings.
±  C has a free-form line structure. End of each C statement must be marked with a semicolon.
±  White Spaces (i.e. tab space and space bar ) are ignored.
±  Multiple statements can be one the same line.
±  Statements can continue over multiple lines.

 C Tokens:-


±  C tokens are the basic buildings blocks in C language which are constructed together to write a C program.
±  Each and every smallest individual units in a C program are known as C tokens.

C tokens are of six types. They are,
°  Keywords   (eg: int, while),
°  Identifiers   (eg: total),
°  Constants    (eg: 10, 20),
°  Strings         (eg: “total”, “hello”),
°  Special symbols   (eg: (), {}),
°  Operators        (eg: +, /,-,*)

 Example :

int main()
{
                int x, y, total;
                x = 10, y = 20;
                total = x + y;
                printf ("Total = %d \n", total);
}

Character Sets:-


±  The character set in C Language can be grouped into the following categories.
°  Letters
°  Digits
°  Special Characters
°  White Spaces
 ±  Letters

§  Upper Case A to Z
§  Lower Case a to z
±  Digits
§  0 to 9
±  White Space
§  Blank Space
§  Horizontal Tab
§  New Line

 Special Characters:-

C program to Find Cartesian Product of Two Sets | C programming

C program to find the Cartesian Product of two sets   Cartesian product  is a mathematical operation that returns a set (or  product set  or simply  product ) from multiple sets. That is, for sets  A  and  B , the Cartesian product  A  ×  B  is the set of all ordered pairs  ( a ,  b )  where  a  ∈  A  and  b  ∈  B . Products can be specified using set-builder notation, e.g. {\displaystyle A\times B=\{\,(a,b)\mid a\in A\ {\mbox{ and }}\ b\in B\,\}.}

Array in C Programming | C Programming

Array in C Array in C Programming The C language provides a capability that enables the user to define a set of ordered data items known as an array. Suppose we had a set of grades that we wished to read into the computer and suppose we wished to perform some operations on these grades, we will quickly realize that we cannot perform such an operation until each and every grade has been entered since it would be quite a tedious task to declare each and every student grade as a variable especially since there may be a very large number. In C we can define a variable called grade, which represents not a single value of grade but an entire set of grades. Each element of the set can then be referenced by means of a number called an index number or subscript. Declaration of arrays Like any other variable arrays must be declared before they are used. The general form of declaration is: type variable-name [50]; The type specifies the type of the elements that will be contained in the array,
