Calculator Assignment (GitHub Classroom)

This repository is a template for a simple calculator assignment. Students can choose their preferred language (Python, C, C++, or Java) and implement the required function.

Getting Started

1. Clone the Repository

git clone <REPO_URL>
cd calculator

Replace <REPO_URL> with your GitHub Classroom assignment link.

2. Select Your Language

• If you want to use Java, keep Main.java and remove main.c, main.cpp, and main.py.
• If you want to use C, keep main.c and remove Main.java, main.cpp, and main.py.
• If you want to use C++, keep main.cpp and remove Main.java, main.c, and main.py.
• If you want to use Python, keep main.py and remove Main.java, main.c, and main.cpp.

You can delete files using:

del main.c main.cpp main.py   # On Windows
rm main.c main.cpp main.py    # On Mac/Linux

(Adjust the command for your OS and language choice.)

3. Update run.sh

• Uncomment the section for your language in run.sh.
• Comment out or remove the other language sections.

4. Implement and Test

• Open your code file and complete the add_numbers (or addNumbers) function.

• Test your code locally:

  • For Java: javac Main.java && java Main
  • For C: gcc -O2 main.c -o calculator && ./calculator
  • For C++: g++ -O2 -std=c++17 main.cpp -o calculator && ./calculator
  • For Python: python main.py

• Check that output.txt matches expected_output.txt:

  • On Mac/Linux (bash):

    diff -wB output.txt expected_output.txt
    

  • On Windows (PowerShell):

    fc.exe /W output.txt expected_output.txt
    

  • On Windows (Git Bash):

    diff -wB output.txt expected_output.txt
    

5. Push Your Solution

git add .
git commit -m "Complete calculator assignment in <your language>"
git push origin main

Once you push your code, GitHub Classroom will automatically run autograding tests. You can see the results in your repository's commit history:

• A green check mark (✓) means your code passed all tests.
• A red cross (✕) means some tests failed.

To view detailed error messages:

1. Go to the Actions tab of your GitHub repository.
2. Click on the failed workflow run.
3. Review the output to see what went wrong.

Note: Do not use any third-party libraries for this project. The goal is to help you understand how computers work internally by implementing everything yourself.
