C is a general purpose, procedural programming language developed in 1972 by Dennis Ritchie at Bell Labs. It is a high-level language that provides low-level capabilities and efficiency. C code can be compiled for different computer architectures, making it portable. It is a structured language commonly used to develop system applications and remains one of the most widely used programming languages.

2.  C is the famous programming language
designed to develop system application
program.

3.  It is known as the starting of every
programming language all the basics of a
program language starts from C language.
 C is known as general purpose procedural
programming language.

4.  Developed by M. Dennis Ritchie at the Bell
laboratories in the year of 1972.
 C is known as high level language because it
has the power of a lower level language and
easy syntax like high level language.

5.  Easy to learn
 It’s a structured programming language

6.  Can handle low level programs
 Compiled code can be used in different
computers

7.  C is a robust language
 C is a highly portable language means once
compiled; the code can be run in any
computer.

8.  Compiler is a computer program that
transforms the human written language into
machine level language.

9.  In general words computer takes the code
written by you and converts it into binary
code.

10.  #include<stdio.h>
#include<conio.h>
void Main()
clrscr();
{
Printf(“my first C program”);
}

11.  #- Prerocessor of program
 Include-Include is a keyword

12.  Stdio.h-Standard input/output header file
 Conio.h-Console input/output header file

13.  Void-is a keyword that collects the garbage
value
 Main()- main() identifies starting of the
program execution

14.  Clrscr()-To clear the console screen
 {, }-Group all statements together
 Printf()-It is a function to print the output on
screen.

15.  Data type of C language mostly divided into 5
major types
 int, char, float, double, void

16. int char float
void double

17.  Int –Used to identify an integer value
 Char- Used to identify a character
 Float- Used to identify floating point type
 Double- Used to identify floating point type
 Void- denotes to type with garbage value

18.  Variable is a stored data memory allocated to
use it in future and we can change the value
too.

19.  Syntax- type variable name;
 Ex- int a, b, c;

20.  Int-Data type
 A, b, c variables

21.  Int-Data type
 A, b, c variables
 ;-Identifies the end of statement.

22.  This is a simple introduction to C basic that will
be elaborated in further classes. If you want to
