What is C language?

1. C Programming language is a powerful general purpose programming

language. It can be used to develop software like operating system,

database, compiler etc. C programming is an excellent language for

beginners to learn to program.

2. C language was developed by Dennis Ritchie to create system

applications that directly interact with hardware devices such as drivers,

kernels, etc.

3. C programming is considered to be the basis of other programming

languages, that is why it is also known as mother language.

4. It is a system programming language. That is to say that it can be used to

do low level programming. It is generally used to create hardware devices,

OS, drivers, kernel etc. For example, Linux kernel is written in C itself.

5. It is a procedure-oriented programming language. Procedure-oriented

programming is known as a function, method, routine, subroutine, etc. A

procedural language specifies a series of steps for the program to solve the

problem. The meaning of procedure is to execute the code written in C line

by line.

6. It is also a Structured programming language. Structure means to break a

program into parts or blocks so that it can be easy to understand.

7. It is a middle-level programming language. The C language program is

converted to assembly code, it supports pointer arithmetic, but it is machine

independent.

Structure of C language code:-

#include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

printf("Welcome in C language!");

getch();

}

In this code

# is a preprocessor which is used to include header file in the program.

include is a directory name which contains header files.

stdio.h means standard input output header file which contains the definition

of function.

conio.h means console input output header file.

void() is a keyword, it means a function does not return any value.

main is a function, it is like a main gate of your house . It is a entry point of

program.

{ is a opening body of main function.

clrscr() this function is used for clear screen. This function does exist in

conio.h header file.

; this is a sami colon, it is used to terminet the statement.

printf() is a function,it is used to display the output on the screen.

getch() it is function, it is used to get the character on screen.

} this is closing body of main function.

A software is required to write the code of this C language and that is Turbo C ++.

I am giving you the link below to download Turbo C ++, you can download it

by clicking on this link-

https://getintopc.com/?s=turbo+c%2B%2B.

When you are trying to write the source code:-

1. Open Turbo C++ editor then write source code.

2. For compile the program Alt+E9 .

3. For run the program Ctrl+F9.

4. To display the output on the screen Alt+F5.

1. Ctrl+F9 - Compile + Run + Display output. When given in the program

getch(); then the use.

We save the code of C in this way like- File-name.c . For example-

demo.c. Here demo is a file name and .c is the extension to save the all
program in C language.

We can run basic program of C without including stdio.h and conio.h header files. If we save a program with extension of .c . But if we need any other function which does not exist in these both header files. It does exist in any other header file then it is compulsary to include and related header files.
