📌 Introduction

C is one of the oldest and most powerful programming languages ever created. It is the foundation of many modern languages like C++, Java, and Python. Before writing your first C program, you must set up the correct environment and understand a few basics about the language.

This guide will help you:

• Understand what C language is

• Learn the history of C

• Learn why C is still important

• Set up a C compiler on Windows, macOS, and Linux

• Install Code::Blocks, VS Code, or Online Compilers

• Write and run your first C program

• Know how a C program works internally

• Practice with exercises

Let’s begin!

What is C Programming Language?

C is a general-purpose, structured, and mid-level programming language developed to build powerful and efficient software.

📜 History of C Programming Language

The history of C is rooted in the evolution of programming languages and computer systems.

✨ Timeline of C Language

1. 1960s – The Birth of BCPL

• Martin Richards created BCPL (Basic Combined Programming Language).

• Purpose: Writing compilers.

2. 1969 – The Creation of B Language

• Ken Thompson modified BCPL to build B language.

• Used in early UNIX systems.

3. 1972 – The Birth of C by Dennis Ritchie

• Dennis Ritchie at Bell Labs created C Language to improve B.

• It added data types, structures, and efficient low-level operations.

• Used to rewrite the UNIX operating system.

4. 1989 – ANSI Standardization

• ANSI standardized C as ANSI C or C89.

• This became the most widely accepted version.

5. 1999 – C99 Standard

• Introduced advanced features like inline functions, variable-length arrays.

6. 2011 & 2018 – C11 & C18

• Latest updates, improved safety and performance.

Why is this history important?

Because:

• C was created to build an operating system → so it is extremely efficient.

• Modern languages evolved from C → learning C makes other languages easier.

• Knowing the history gives you deep understanding of its design and usage.

---

✨ Key Features of C

• Fast and efficient

• Portable (runs everywhere)

• Structured (easy to break code into modules)

• Foundation for many modern languages

• Used in operating systems, embedded systems, compilers, databases, and more

---

✨ Where is C used today?

• Operating Systems (Windows, Linux kernel)

• Embedded systems

• Game engines

• Database systems (MySQL)

• Compilers and interpreters

• Device drivers

How C Programming Works Internally

C is a compiled language, meaning code must be converted into machine code using a compiler.

The process:

1. Write code → .c file

2. Compile code → checks errors

3. Link libraries → creates executable

4. Run the program → .exe or output file

Setting Up C on Windows

There are multiple ways to install a C compiler on Windows. Here are the best ones:

---

Method 1: Install Code::Blocks (Easiest for Beginners)

Steps

1. Search: “Code::Blocks MinGW download”

2. Download codeblocks-20.03mingw-setup.exe

3. Install it → Make sure MinGW compiler is selected

4. Open Code::Blocks

5. Create a new C project

Why Code::Blocks?

• Compiler included

• Beginner-friendly

• Simple interface

---

Method 2: Install GCC Compiler with VS Code (Recommended)

You need:

• VS Code

• MinGW-w64 compiler

Steps:

1. Download VS Code

2. Install MinGW-w64

3. Add MinGW bin path to System PATH

4. Install C/C++ Extension

5. Create a file hello.c

6. Compile:

gcc hello.c -o hello

7. Run:

hello

---

Method 3: Use Online C Compilers (No Setup Needed)

If your PC is slow, use:

• Replit

• Programiz

• OnlineGDB

• GeeksforGeeks IDE

Just write and run instantly.

---

Setting Up C on macOS

macOS already includes a compiler.

Steps:

xcode-select --install

Compile:

gcc file.c -o file

---

Setting Up C on Linux

Install GCC:

sudo apt install build-essential

Compile:

gcc hello.c -o hello

---

Write Your First C Program

hello.c

#include <stdio.h>

int main() {
    printf("Hello, World!");
    return 0;
}

Output:

Hello, World!

---

Understanding the Structure of a C Program

1. Header File

#include <stdio.h>

Used for input/output.

2. main() Function

Entry point of the program.

3. printf()

Displays output.

4. return 0;

Program ended successfully.

---

Exercises

Q1. Print your name using C.

Expected output:

My name is ______.

Q2. Create a program to print:

Welcome to C Programming!

Q3. Write a program to print two numbers.

Example output:

5
10
