Introduction to C

• C is a procedural programming language.
• It was initially developed by Dennis Ritchie in the year 1972.
• It was mainly developed as a system programming language to write an operating system.
• The main features of the C language include :
  • low-level memory access
  • simple set of keywords
  • clean style
    these features make C language suitable for system programmings like an operating system or compiler development.
• Many later languages have borrowed syntax/features directly or indirectly from the C language
  • Like syntax of Java, PHP, JavaScript, and many other languages are mainly based on the C language.
  • C++ is nearly a superset of C language (Few programs may compile in C, but not in C++).

Basic C Glossary

These are glossarry for some of the keywords, functions and terms used in this programs :

Header Files

In C language, header files contain the set of predefined standard library functions. The “#include” preprocessing directive is used to include the header files with “.h” extension in the program. Here is the table that displays some of the header files used in the programs:

Header files	Description	Example of contained functions
stdio.h	Input/Ouput functions	printf();, scanf();
conio.h	Console Input/Output functions	getch();, clrscr();
stdlib.h	General utility functions	malloc();, realloc();
math.h	Mathematics fuctions	sqrt();, pow();
string.h	String functions	strcpy();, strcmp();

main() Function

main is a predefined keyword or function in C. It is the first function of every C program that is responsible for starting the execution and termination of the program. It is a special function that always starts executing code from the main having int or void as return data type.

List of Programs

The list of Programs are divided into two parts .

• Part-1 consisting of basic C programming.
• Part-2 consisting of data structures of C programming.
