Variables In programming, a variable is a container (storage area) to hold data. To indicate the storage area, each variable should be given a unique name (identifier). Variable names are just the symbolic representation of a memory location. For example: Here, abc is a variable of int type. Here, the variable is assigned anContinue Reading
C Constants are also like normal variables. But, only difference is, their values can not be modified by the program once they are defined. Constants refer to fixed values. They are also called as literals Constants may be belonging to any of the data type. Syntax: const data_type variable_name; (or) const data_type *variable_name;Continue Reading
C tokens, Identifiers and Keywords are the basics in a C program. All are explained in this page with definition and simple example programs. 1. C TOKENS: C tokensare the basic buildings blocks in C language which are constructed together to write a C program. Each and every smallest individual unitsContinue Reading
C data types are defined as the data storage format that a variable can store a data to perform a specific operation. Data types are used to define a variable before to use in a program. Size of variable, constant and array are determined by data types. Programming C – DATAContinue Reading
printf() and scanf() functions are inbuilt library functions in C programming language which are available in C library by default. These functions are declared and related macros are defined in “stdio.h” which is a header file in C language. We have to include “stdio.h” file as shown in below C programContinue Reading
Once the coding is completed, the program is feed into the computer using a compiler to produce equivalent machine language code. In C compilation two parts are there namely 1) Compiler and 2) Linker. Compiler receives C source file as input and converts the file into object file. Then theContinue Reading
Classification of Programming Language Programming language can be classified into 2 types 1. High Level Language and 2. Low Level Language. High Level Language:- Those are more English like language and hence the programmers found them very easy to learn to convert the programs in high level language to machineContinue Reading
C is a programming language it is designed by DENNIS RITCHIE in 1972 at AT & T [American Telephone and telegraphs] Bell labs in USA. C is most popular general purpose language. BRIEF HISTORY OF C LANGUAGE: In 1960’s COBOL was being used for commercial applications and FORTRAN forContinue Reading
