Introduction to c programming language

1. An Introduction to C
Programming Language

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

3. Intro
 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. History
 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. Why C used as a professional
programming language?
 Easy to learn
 It’s a structured programming language

6. Why C used as a professional
programming language?
 Can handle low level programs
 Compiled code can be used in different
computers

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

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

9. What is Compiler?
 In general words computer takes the code
written by you and converts it into binary
code.

10. Structure & Syntax of a C
Program
 #include<stdio.h>
#include<conio.h>
void Main()
clrscr();
{
Printf(“my first C program”);
}

11. Description of Code:-
 #- Prerocessor of program
 Include-Include is a keyword

12. Description of Code:-
 Stdio.h-Standard input/output header file
 Conio.h-Console input/output header file

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

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

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

16. C Data types
int char float
void double

17. C Data types
 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:-
 Variable is a stored data memory allocated
to use it in future and we can change the
value too.

19. Variable:-
 Syntax- type variable name;
 Ex- int a, b, c;

20. Explanation of Example
 Int-Data type
 A, b, c variables

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