Turbo C++ is an Integrated Development Environment (IDE) and compiler suite for the C++ programming language. Turbo C++ was initially developed by Borland and released in 1990.

It was mainly designed for the MS-DOS operating system, allowing developers to write C++ applications in a console-like environment.

However, you may encounter an instance where you need to install and use the Turbo C++ environment on the latest Windows versions.

This tutorial will show you how to quickly install and run the Turbo C++ compiler on the latest Windows versions, such as Windows 7, 8, 8.1, 10, and 11.

Components of Turbo C++

Turbo C++ consists of several components:

1. The Integrated Development Environment (IDE): This graphical user interface allows you to write, edit, compile, and debug code. The IDE includes code highlighting, auto-completion, and project management tools.
2. The C++ Compiler: The compiler is responsible for translating the source code into executable machine code that can be run on a computer. The Turbo C++ compiler uses the C++ language standard and includes support for the Standard Template Library (STL).
3. The Turbo Debugger: The debugger allows us to test and debug our code. It allows us to review their code line-by-line and inspect variables and memory contents.

How it Works

Turbo C++ works by taking the source code written by the developer and compiling it into executable machine code. The compiler uses several different stages to accomplish this task.

1. Lexical Analysis: The compiler first analyzes the source code to identify the individual tokens that make up the program. These tokens include keywords, identifiers, operators, and literals.
2. Syntax Analysis: Once the tokens have been identified, the compiler checks the program’s syntax to ensure that it conforms to the rules of the C++ language. This involves checking that statements are properly structured, that all brackets are balanced, and that variable types are used correctly.
3. Semantic Analysis: After the syntax has been checked, the compiler performs a semantic program analysis. This involves checking that all variables have been declared, that functions have been defined correctly, and that there are no type mismatches.
4. Code Generation: Once the semantic analysis is complete, the compiler generates the executable machine code that can be run on a computer. This involves translating the C++ code into a low-level language that the computer’s processor can understand.

How to Install Turbo C++ on Windows

Let us now dive into the steps we can use to install Turbo C++ on Windows.

Step 1 - Download Turbo C++

The first step is to download the Turbo C++ installer.

Open your browser and head over to the resource below:

https://github.com/vineetchoudhary/TurboCPP/releases/tag/v3.2

Before extracting the downloaded installer, ensure you do not have a previous installation of the Turbo C++ compiler.

Step 2 - Extract the Zip Archive

Once the download is complete, extract the archive to any desired location.

Step 3 - Run the Installer

In the extracted directory, open the setup.exe file. This will launch the installer Wizard allowing you to install Turbo C++ on your machine.

Accept the Licenses and click Next.

Finally, click Install to proceed with the install.

Launch Turbo C++

Once the installation is complete, you can select the Launch the Program option from the installer page or click on the Turbo C++ icon from the Desktop.

To launch the Turbo C++ in DOS mode and full screen, select the Start Turbo C++ on the start window.

Hello World Program in Turbo C++

To create a simple program in Turbo C++, select New Source File from the Main Window.

This will prompt you to give the name to your source file. Choose the target directory, provide a name for your source file and click save.

By default, the program will launch in Full Screen mode.

If you do not want full-screen mode, uncheck the “Full-screen mode” check box on the main window.

Edit the source code and add the hello world program as:

#include <iostream.h>

int main()
{
    cout << "Hello World!" << endl;
    return 0;
}

Press F2 or Head over to File -> Save from the top bar to save the file.

Finally, to compile the program, press F9.
