History Of C The milestones in C's development as a language are listed below:• UNIX developed c. 1969 -- DEC PDP-7 Assembly Language

• BCPL -- a user friendly OS providing powerful development tools developed from BCPL. Assembler tedious long and error prone.

• A new language ``B'' a second attempt. c. 1970.• A totally new language ``C'' a successor to ``B''. c. 1971• By 1973 UNIX OS almost totally written in ``C''.

Characteristics of C We briefly list some of C's characteristics that define the language.• Small size• Extensive use of function calls• Loose typing -- unlike PASCAL• Structured language• Low level (Bitwise) programming readily available• Pointer implementation - extensive use of pointers for memory, array, structures and functions.



Reasons for Being A Professional Language

C has now become a widely used professional language for various reasons.• It has high-level constructs.• It can handle low-level activities.• It produces efficient programs.• It can be compiled on a variety of computers.

Variables In CC variable is a named location in a memory where a program can manipulate the data. This location is used to hold the value of the variable. The value of the C variable may get changed in the program.



Constants In C ANSI C allows you to declare constants. When you declare a constant it is a bit like a variable declaration except the value cannot be changed.



Data Types In C

C has a concept of 'data types' which are used to define a variable before its use. The definition of a variable will assign storage for the variable and define the type of data that will be held in the location.

The value of a variable can be changed any time.



Different Data Types in C• C has the following basic built-in data types.• int• float• double• char



Operators in CAn operator is a symbol that tells the compiler to perform specific mathematical or logical functions. C language is rich in built-in operators and provides the following types of operators −• Arithmetic Operators• Relational Operators• Logical Operators• Bitwise Operators• Assignment Operators• Misc Operators

Control Statements In CA control statement is a statement that determines whether other statements will be executed. An if statement decides whether to execute another statement, or decides which of two statements to execute. A loop decides how many times to execute another statement. C provides two styles of flow control:• Branching• Looping



1. BranchingBranching is so called because the program chooses to follow one branch or another. Branching is deciding what actions to take.• If Statement• If Else Statement• Switch Statement



2. LoopingLoops provide a way to repeat commands and control how many times they are repeated. C provides a number of looping way. looping is deciding how many times to take a certain action.• For Loop• While Loop • Do While Loop



Functions in CA function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions.



Array in CArrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.



Strings In CStrings are actually one-dimensional array of characters terminated by a null character '\0'. Thus a null-terminated string contains the characters that comprise the string followed by a null.



Pointers in CA pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location.



Structures in C• Arrays allow to define type of variables that

can hold several data items of the same kind. Similarly structure is another user defined data type available in C that allows to combine data items of different kinds.

• Structures are used to represent a record. Suppose you want to keep track of your books in a library.



Unions In CA union is a special data type available in C that allows to store different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple-purpose.
