How to install Turbo C++: Compile and Run a C Program

First thing you need to understand is that computer (Machine) can only understand Machine language (Stream of 0s and 1s). In order to convert your C program source code to Machine code, you need to compile it. Compiler is the one, which converts source code to Machine code. In simple words you can say that a compiler converts human readable code to a machine readable format.

Install Turbo C++: Step by Step Guide

Download link: Download Turbo C++ for Windows

Step 1: Locate the TC_DOS.exe file and open it. You will find it at location C:\TurboC++.

Step 2: File > New (as shown in above picture) and then write your C program

#include<stdio.h>
int main()
{
       printf("hello World!");
       return 0;
}

Step 3: Save the program using F2 (OR file > Save), remember the extension should be “.c”. In the below screenshot I have given the name as helloworld.c.

Step 4: Compile the program using Alt + F9 OR Compile > Compile (as shown in the below screenshot).

Step 5: Press Ctrl + F9 to Run (or select Run > Run in menu bar ) the  C program.

Step 6: Alt+F5 to view the output of the program at the output screen.

Compile and Run C program using gcc compiler

We have seen the steps to compile and execute a C program using Turbo C++. We can also do the same using gcc compiler. The steps are as follows:

Source code Helloworld.c (file should always be saved with .c extension)

# include<stdio.h>
int main()
{
         puts ("hello World");
         return 0;
}

Compile it (it is basically converting a helloworld.c file to a helloworld file)

>gcc  helloworld.c  –o  helloworld
>

The generated file would be helloworld.exe if you are compiling on windows.

Run the compiled program
Once you give the above command, a .exe file would have been created if you are on windows then type the following command to run the source code.

For Windows

>helloworld

For Mac and Linux OS

>./helloworld

gcc compiler took the human readable format (helloworld.c file) and converted into a machine code for Windows, Linux and Mac OS X.
