What is c programming-explain along example and basic knowledge about C Programming language

What is C prograammng?

 C programming is one of the most powerful programming languages. It is developed by Dennis Ritchie at Bell Laboratories in 1972. The C programming language is structure programming language and general purpose programming language as well. It is a highly efficient programming language and easy to learn. It has both properties high-level language and low-level language. It is the most powerful programming language because it is used to develop software as well as programs.

Your first c programming

             Write a program to print 'Welcome' on display 

           

Output

 (1) Header files

In c header files are used to function definition. which is using #include

#include<stdio.h>: It is a standard input output header file. It contains the function definition of input-output functions such as scanf(), printf() etc.

#include<conio.h>: It is a header file, which is included in the program this isUsed to use, clrscr(), getch(), etc. We do not need to include this file in the C program. 

#include<math.h>: This header file is used for mathematical functions such as pow(), sqrt(), sin(), tan(), cos() etc.

 #include<string.h>: It is string header file.It use for string manipulation. It contains   the     function definition of string processing functions such as strlen(), strcat(), strcpy()   etc. 

(2) void main():- Every C program should begin with main(). Thus void main() is the starting point of the program.

(3) printf():- It is used to display the conversation characters along with some unchanged character.

\n:- It used to print on the new line.

Operators in c:

Arithmetic operators

operators                meaning                                          example

+                           Addition                                             a+b

-                           subtracting                                          a-b 

*                          Multiplication                                      a*b

/                           Division                                               a/b

%                         Modulus                                              a%b

Relational operators

operators                meaning                                          example

<                          less than                                               a<b

>                          Greater than                                         a-b 

<=                        less than or equal to                             a<=b

>=                        Greater than or equal to                      a>=b

==                        Equal to                                              a==b

!=                         is not equal to                                     a!=b

Logical operators

operators                meaning                                          example

&&                        Logical AND                                     a&&b

||                            Logical OR                                         a/b

!=                         Logical Not                                         a!=b

Data type

The data type is a way of the hold of data in the C language.

Basic data type 

Variable type                          keyword                  Format conversation specifics

Character                                    char                    %c

Integer                                         int                      %d

Float                                           float                    %f
