C was developed by Dennis Ritchie in 1972 and is a procedural programming language that is the predecessor to many popular languages today like C++, C#, and Java. C code is run using software like Turbo C or Borland C and uses file extensions like .c to indicate the language. A simple C program uses #include to access library functions like printf and outputs "Hello world".

C Programming Developed by Dennis ritchie in the year of 1972
C ? C is the successor of B(BASIC) and A(ALGOL) languages. ? Most Popular language for over 3 decades (30+ years) ? C is a Procedure oriented programming language ¨C i.e. data should be assign first like ¨C Data then function.
Why we have to learn C? 1. To better understand other languages. - Like:- c++, c# and java. 2. To understand how data flow with in the compiler. 3. To development of coding logic.
Software are used to run c language code. ? Turbo c or turbo c++ ? Auto C ? Borland C ? These software run .c extension files which tell the compiler or interpreter that .c file is a file that belongs to c language ? Like for c++ its .cpp ? For java its .java ? For c# its .cs extension files.
Lets understand C by a simple Code. #include<stdio.h> or #include¡±stdio.h¡± #include<conio.h> or #include¡±conio.h¡± Void main() { printf(¡°Hello world¡±); } Output: Hello world Note: #include is preprocessor which tell compiler to search the directory(library files) within <stdio.h>, ¡°conio.h¡± Here stdio.h is a library file which contain printf() function.
