Introduction to C programming language in easy words
## What is C Programming?
C is a powerful, general-purpose programming language that is widely
used for developing a variety of applications, from operating systems like
Windows to complex programs like the Oracle database, Git, and Python
interpreter[1][2][4][5]. It was originally developed in the early 1970s by
Dennis Ritchie at Bell Labs for writing the Unix operating system[1][3][4].
C is a structured programming language that is organized around
functions and modules. It supports features such as loops, conditionals,
and functions, allowing programmers to write efficient and well-organized
code[6][7]. C is known for its simplicity, efficiency, and portability,
meaning that programs written in C can run on different computer
architectures with minimal changes to the source code[1][3].
## Basic Structure of a C Program
A typical C program consists of the following components[5][7]:
1. **Header file inclusion**: C programs often include header files (e.g.,
`stdio.h`) which provide access to functions and data types needed for
input/output and other common operations.
2. **`main()` function**: This is the entry point of the program where
execution begins. It is defined with the `int main()` syntax.
3. **Function body**: The body of the `main()` function is enclosed in
curly braces `{}` and contains the statements that make up the program.
4. **Statements**: These are the individual instructions that perform
specific tasks, such as printing output or performing calculations.
Statements are terminated with a semicolon (`;`).
