C Programming Environment Setup

To start programming in C, you need to have an environment where you can write, compile, and run your code. This tutorial will guide you on how to set up your C programming environment.

Step 1: Installing a Text Editor

A text editor is a tool where you write your code. There are many text editors available, but for beginners, Notepad++ for Windows users, and TextMate for Mac users are good places to start.

Notepad++: You can download it from this link. After downloading, just follow the installation wizard instructions.
TextMate: It can be downloaded from this link. After downloading, drag the application to your applications folder.

Step 2: Installing a C Compiler

The C Compiler is a tool that translates your code into a language that your computer can understand. For C programming, we'll use GCC (GNU Compiler Collection).

Windows: Install MinGW. It's a software with GCC. Download it from this link. After downloading the .exe file, run it and follow the installation wizard.
Mac: GCC comes pre-installed. You can check it by typing gcc --version in your terminal. If it's not installed, you'll need to download the Xcode Command Line Tools. You can do this by typing xcode-select --install in your terminal.

Step 3: Setting up Path for Compiler

This step is only for Windows users. You need to set up the path for the compiler to run it from the command prompt.

Search for 'Environment Variables' in your system (Control Panel > System and Security > System > Advanced system settings > Environment Variables).
Under 'System Variables', find and select 'Path' then click 'Edit'.
In the 'Edit environment variable' dialog box, click 'New'.
Type the path of your 'MinGW\bin' folder (Usually, it's C:\MinGW\bin).
Click 'OK' in all dialog boxes.

Now, you can run the GCC from the command prompt.

Step 4: Writing a Simple C Program

Let's write a simple C program to check if your environment is set up correctly.

Open your text editor and type the following code:

#include <stdio.h>

int main() {
    printf("Hello, C world!\n");
    return 0;
}

Save the file with a .c extension (for example, hello.c).

Step 5: Compiling and Running the C Program

Windows: Open the command prompt, navigate to your program's directory, and type gcc hello.c -o hello. This will create an executable file named hello.exe. Run it by typing hello in the command prompt.
Mac: Open your terminal, navigate to your program's directory, and type gcc -o hello hello.c. This will create an executable file named hello. Run it by typing ./hello in the terminal.

If you see Hello, C world! printed on your screen, congratulations! You have successfully set up your C programming environment. Happy coding!
