The C language was first developed by
Ken Thompson
Dennis Ritchie
In the beginning they developed programming language called B.
After doing some alterations they have developed a new language called C.

EXAMPLE PROGRAM :
Lets consider a simple program
#include<stdio.h>
main()
{
printf("Hello world");
}
Printf("Hello world");
- This line indicates that we want to execute the string "Hello world".
- printf is an inbuilt function used to execute the data that we have written.
- While printing the, the data to be printed should be typed between double quotes
- Every function should have round brackets() , ended with a semicolon ;
Printf is an inbuilt function. But how can we call it?
To call this inbuilt function we use stdio.h
stdio.h
- stdio - Standard input output
- h - header file
- Header file has the definition of all the functions.
- Definition for the function printf(); will be available in the stdio file
include
- To include the header file we use include
#
- # is the preprocessor
- Preprocessor is used to include all the files before execution.
main()
- A C program can't be executed without a main function
- The CPU first executes the main function first.
