What is a C programming language?

In this little blog we will discuss about, "what a C language is?" and "what are it's features?" in very brief just to gain some basic knowledge about a C program. C is a programming language which is considered to be a very very useful tool for a programmer but before discussing about what is a C program, let's first talk about, basically what a program is?
     In very simple language, "a program is a set of instructions which execute step by step sequentially."

C Programming Language

C was first developed in 1970’s at Bell Laboratories by Dennies Ritchie. Initially it was designed for programming in UNIX  operating system. Later in 1982, ANSI formed a committee to standardize the C language and finally in 1989 the standard for C language was introduce known as ANSI C.

Now let’s talk about its features:

• C is known as the middle level language, because it lies between II^nd generation language and III^rd generation language.

• C has got pre-defined structure and programmer should always follows the same predefined structure.

• C is a function based language ie. to execute a data we must use a pre-defined C functions.

• It has building block diagrams because the program is divided into many small blocks so that it becomes easier to execute a program correctly.

• C is a case sensitive programming language  ie. 'A' and 'a' are two different character to C.

Syntax: # include<stdio.h> main() { Statement 1; Statement 2; Statement 3; }

                    

 { = Opening braces

 } = closing braces

 ; = line terminator

 # = preprocessor
stdio=standard input/output file

.h = header file
<stdio.h>= to take I/P and O/P

 main( )=Very first function of c to start c program.


Data Types
   
C supports different types of data, the basic data types used in C are :

int	2 bytes
char	1 byte
float	4 bytes
double float	8 bytes

A simple C program

#include<stdio.h>

main()

{

printf("Hi \n");

printf("Welcome to Vikram Malla Blogs");

}

this is what actually a program does looks like in a compiler..

this is how the output do looks like once after it is executed.....
