How to compile and run C code in Notepad

To compile and run C in Notepad , install g (via MinGW), write code, then configure Run command with: cmd /k g "$(FULL_CURRENT_PATH)" -o "$(CURRENT_DIRECTORY)$(NAME_PART)" && "$(CURRENT_DIRECTORY)\$(NAME_PART).exe", save as shortcut (e.g., Ctrl F10) for execution.

To compile and run C code in Notepad , you need to use an external compiler (like MinGW or g ) and configure Notepad to execute the compilation and running commands. Here's how you can set it up step by step.

1. Install a C Compiler (g )

You must have a C compiler installed on your system. The most common choice for Windows is MinGW (Minimalist GNU for Windows), which includes g .

• Download MinGW-w64 from https://www.mingw-w64.org/ or use MSYS2 to install it.
• During installation, make sure to add the bin directory (e.g., C:\mingw64\bin) to your system's PATH environment variable.
• Verify installation: Open Command Prompt and type g --version. If you see version info, it’s working.

2. Write Your C Code in Notepad

Open Notepad and write a simple C program, for example:

#include <iostream>
using namespace std;

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

Save the file with a .cpp extension, like hello.cpp.

3. Configure Notepad to Compile and Run

Use Notepad 's Run feature to call external commands.

1. Press F5 or go to Run → Run...
2. To compile and run, enter this command:

cmd /k g   "$(FULL_CURRENT_PATH)" -o "$(CURRENT_DIRECTORY)\$(NAME_PART)" && "$(CURRENT_DIRECTORY)\$(NAME_PART).exe"

• $(FULL_CURRENT_PATH): Full path of the current file.
• $(CURRENT_DIRECTORY): Folder of the file.
• $(NAME_PART): Filename without extension.
• cmd /k: Keeps the command window open after execution.

Click Save, give it a name like Compile & Run C , assign a shortcut (e.g., Ctrl F10), then click OK.

4. Use the Shortcut to Compile and Run

Now, whenever you want to compile and run your C code:

• Press your saved shortcut (e.g., Ctrl F10).
• A command prompt will appear showing compilation errors (if any) and run the output.
• If there are no errors, you’ll see your program’s output (e.g., "Hello, World!").

Basically, Notepad acts as a lightweight editor while relying on g and the command line to do the actual compiling and running. It's not a full IDE, but it works well for small projects and learning.
