Identifiers used In C                  A c program consists of two types of elements, user defined and pre-defined.identifier is nothing but a name given to those elements. An identifier is a word used by programmer to name a variable,function or label.identifiers consists of letters and digits,in any order , except that the first character must be a letter.Both upper and lowercase letters can be used. Identifiers are :- 1.  Keywords. 2.  Variables. 3.  Constants. 4.  Numbers. 5.  Data types keywords :-               Keywords are nothing but system defined identifiers. Keywords are reserved words of the language.they have specific meaning in the language and cannot be used by the programmer as variable or constant names. c language specifies 32 keywords and other reserved keywords. Keywords are listed below : auto If r...

Introduction to C Programming language              C is a high level,general purpose,structured programming language.instructions of c consist of terms that are very closely same to algebraic expressions,consisting of certain English keywords.  By design, C provides constructs that map efficiently to typical  machine instruction  and has found lasting use in applications previously coded in  assembly language . Such applications include  operating systems  and various  application software  for computers, from  supercomputers  to  embedded systems .              C was originally developed at   Bell Labs  by  Dennis Ritchie  with their colleague Ken Thompson between 1972 and 1973 to make utilities running on  Unix . Later, it was applied to re-implementing the kernel of the Unix operating system. During the 19...

 Simple Program To Find Square Of A Given Number     It is the one of the simple programs. In this we have used very simple logic of finding square of a given number which we have studied in school. The logic is very simple as below :-           square of 2 = 2 * 2,           that means square of no = no * no we have implemented it in following program : Code :-              #include<stdio.h>             #include<conio.h>             void main()             {                int n,sq;                printf("Enter a Number: ");                scanf("%d",&n);                sq = n * n; ...
