Tutorial : How to run Turbo C in DosBox ?

Many are asking where to get Turbo C that is compatible for their Windows 7 computers. Turbo C is still running on Windows 7 but it doesn’t allow me to enter full screen just like the old days of windows. But using some applications like DOSBox, will allow us to use Turbo C in fullscreen mode.

Follow this guide on how to run Turbo C with DOSBox.

In this guide, I have already installed Turbo C on my computer.
Now, let’s proceed to the guide.

You must have DosBox installer first. You can download it from the link below.
Dosbox DL link : http://www.dosbox.com/download.php?main=1

Dosbox Installation:

1. Run DosBox installer.

2. Just click Next until the installation folder selection then click Install.

 

 

 

3. After the installation process is completed, close the installation window.

You are done installing DOSBox.

We are now going to make DOSBox to run Turbo C everytime you run DOSBox.

I have read the manual of DOSBox and found out the following procedure that will let us run Turbo C much easier, instead of typing commands just to run Turbo C or any program.


4. After installing DOSBox, right click on DosBox shortcut icon on your desktop and click Properties.

5. In Shortcut tab, we will edit the target textbox and put the following command:

"C:\Program Files\DOSBox-0.74\DOSBox.exe" C:\TC\BIN\TC.exe -c "mount T C:\TC\BIN "

6. Click Apply and OK to close the window.

You can now run Turbo C and use it like old times.

NOTE: The instructions above (Step 5) will work only if the installation path of DOSBox and Turbo C are correct, or you will have to edit the path where you installed DOSBox and Turbo C.

Turbo C: Variables and User Input

Getting input value

In every program, variables are declared and used for the user inputs. From my previous post, we already know how to declare variables, but those variables are static or cannot be changed when we run our program.


This time, we are going to create a program that will let the user to input the value. This basic program will ask the user to enter a value that will be set to our variables, and then the program will get the sum of two inputs.

Code:

By using the scanf(“%d”, &x) we are able to get the user input. (“%d”, &x) will get an integer value of the input and will be assigned in variable x.

Turbo C : Variable Declaration

Declaring Variables

Variables are used to hold a value. It can be a text or numbers or even both. This is very useful in programming especially when you want to display some text/numbers multiple times.

There are types of variables used to make a program. These will give the variables a classification that the computer will understand.

On this part, we will create a simple mathematical addition. Here is the code.

Looking at the codes, we used int type of variable. It is used because we are using variables to hold numeric values.

x, y and z are the variables that we declared. You can use any alphanumeric characters to declare variables. It can be (A, B, C) , (num1,num2,num3),  or it can be a name of your choice.

The x has a value of 100 and y has 200, but z doesn’t have a value. It’s ok, we can declare a value for z later.

printf("Value of X is = %d \n", x);       //---- %d will call the integer value of x

printf("Value of Y is = %d \n", y);       //---- %d will call the integer value of y

This statement will display a text and a variable.

The backslash followed by letter n “\n” will begin a new line.

z=x+y;

printf("The sum of X and Y is = %d", z);

This line will declare the value of z.  z=x+y , it is clear that the value of z will add  the  value of x and  y. And the last part will print the value of z.

Output:

Turbo C : Hello World

Writing Hello World Program

To write a C program, we need a compiler. You can use compilers like DevC++ and CodeBlocks but Turbo C is indicated in our title, so we are going to use "Turbo C". I prefer using Turbo C because some codes doesn't work with the new compilers. You will see what I mean if you try to use different compilers. If you still don't have turbo c, you can download it here (link).

This is a basic program written in C Language. This program will just print the hello world text. It simply show you the basic structure of a program and the use of printf function.


#include<stdio.h>
#include<conio.h>

void main()
{
clrscr();
printf("HELLO WORLD");
getch();
}

The first two lines are the libraries. There are lots of libraries
that is used to create a program. It is used to allow the functions
that we use in every program.

clrscr() - it clears all previous text displayed.
Printf("hello world") - a function to display a text. The function
that is most important in every program.
getch() - without this, your program will just flash on your screen.

Output:

C++ : Hello World!

Writing Hello World program in C++

Hello world, this is the first program or the first step in learning on how to display a text. Text is very important to any program. It gives users idea on how to or what to do with the program. Anyway, we all know what is text for... LoL :)

To write a code, you can just use notepad or any text editor. But, it can't be a program until you compile it.
To make it simpler, we can just use a compiler to write and build a program. You can find several compilers around the internet, you can download and try each of them to see which one is better for you.
I use Dev C++ as  a compiler. You can download it here (download link).

Here is the code:

#include <iostream.h> using namespace std; int main() { cout << "Hello Dude!"; cin.get(); }

This code will just simply display "Hello Dude!". 

Don't be confused if its called Hello World program but we wrote "Hello Dude!". The main goal of this code, is to show you on how to display a text. You may say that this is just a simple codes to show a text, but this is very important in writing a program. Just imagine a keyboard without any characters printed on it. :)

Download: Freeware - Turbo C 3.0

Turbo C for XP / Windows 7 / Windows 8

Turbo C is an IDE(Integrated Development Environment) and a compiler for the C programming language from Borland. It is 1st introduced in 1980's. Turbo C is known for its outstanding features and easy to use. It was developed and released with many versions. It has a small size that is easy to install, a fast compiler that helps the programmer to build their programs faster, and a it is very cheap.

It is one of the most popular and used by lots of the programmers during its time. Year 2006, it was re-released as freeware. But until now, Turbo C is still used for teaching C programming in computer schools.

And still, lot of programming students or beginners in C programming or those who want to learn C programming are looking for Turbo C Installer. You can find a link below and download this freeware program.


NOTE:
• Latest version of windows doesn't support full screen on Turbo C. If you want to run this in FULLSCREEN, you have to use DOSBox as emulator. (See link below)
