Variable & Datatype for C-programming                                   5 Variable:- Whose value change is known as variable.You can use some specific variable. Ex:-a,b,c        A,B,C        a1,b2 But 1a,2b, space, special character are  not allowed. Underscore is allowed. Datatype:- Before declaration variable you need to define the type of variable i.e. integer, character, float etc Variable declaration:- You can define a variable in following way. Syntax:- datatype  variablename; Eg:-int x;        int a;        float q; Variable intialization:- In this step you have to give the value of variable. During character intialization write character within the '   ' Eg:-int x=1; or int x; x=1;       Datatype:- Datatype definition the nature of variable. It is mainly three types. 1.Integer 2.Character 3.Float 1.Integer datatype:- It represent integer value. And expressed as %d; Data Type      Size in bytes

      Syntax of C-programming                                4. A C program is divided into different sections. There are six main sections to a basic c program.  The six sections are, Documentation Link Definition Global Declarations Main functions Subprograms 1. Documentation:- The documentation section is the part of the program where the programmer gives the details associated with the program. He usually gives the name of the program, the details of the author and other details like the time of coding and description. It gives anyone reading the code the overview of the code. 2.Link Section:- This part of the code is used to declare all the header files that will be used in the program. This leads to the compiler being told to link the header files to the system libraries. 3.Definition Section:- In this section, we define different constants. The keyword define is used in this part. 4.Global Declaration Section:- This part of th

                                      3. Errors in C-language Syntax error Logical error Math error Run time error Linker error Semantic error 1.Syntax error:-                                If any changes made in the predefined format of a c-language then the error is called  syntax error. Eg:- If semicolon missing or printf,scanf or other keyword are missing comes under syntax error. 2.Logical error:-                                   This error occurs when the user gets and an unaccepted output. Eg:- If the program is expected to give the output in real number but we are getting the output in integer. 3.Math error:-                             This error occurs because of the illegal input. Eg:- An number divided by zero is illegal modulus  operator  will not work for floating value. 4.Run time error:-                                    An error occurs at a time of exception is known as run time error. Eg:- In the syntax of scanf & i

                                       2.               Language Translator 1. Assembler 2. Compiler 3. Interpreter 4. Linker 5. Loader 1.Assembler:-   In computer science, assembler is a program which convert assembly level language into machine level language, because computer understand binary language.                          Machine code                                     ⬆️                                     ⬆️                               Assembler                                     ⬆️                                     ⬆️                    Assembly Level language 2. Compiler:-  Compiler turns the high level language to binary language or machine code at only one time is known as compiler.  3.Interpreter:- An  is also a program like compiler it convert assembly language to binary language but an interpreter goes one line of  a code a at time. 4.Linker:-   linker is used to link multiple obj files to create an executable file

              Introduction of C-language                                           1. C-language was developed by  Dennis Ritchie  . In the year  1972  in  Bell Laboratory  in  USA  . C language suitable for system programmings ,it was mainly developed for  UNIX operating system . Dennis Ritchie (1941-2011) Books:-   The C Programming languages Dennis Ritchie also known as father of C-language.                         Use of C-language  👉🏿Operating system.  👉🏿Language Compiler.  👉🏿Text editor.  👉🏿Modern Program.  👉🏿Database.  👉🏿Language interpreter.  👉🏿Mobile & desktop application.  👉🏿 Gaming & Animation.                Features of C-language 👉🏿 Compiler based. 👉🏿Case sensitive. 👉🏿 Simple & Powerful. 👉🏿 Syntax based. 👉🏿 Structure oriented. 👉🏿 Middle level.
