GCH C++ (VS Code & GitHub Codespaces)

This is a repository for a GitHub Copilot for Business Hackathon with C++

⚒️What are we building

We are building a interest calculator together with a unittest.

Prerequisites

This introduction is written for VSCode/GitHub Codespaces. Please install the following extentions.

• C/C++
• GitHub Copilot
• GitHub Copilot Chat (will install automatically)

In addition, please execute the following commands in the terminal:

sudo apt-get update
sudo apt-get install libgtest-dev

To use GitHub Copilot, you must have an active subscription for GitHub Copilot in your personal account, or you need to be assigned a seat by your organization. Sign up for a GitHub Copilot free trial in your personal account.

⌨️ Nice to know: GitHub Copilot Shortcuts

Shortcut	Description
Ctrl+i	Open inline chat
Ctrl+Alt+i	Move to chat
Ctrl+Enter	Accept code suggestion from chat

Scenario 0️⃣: Start with Copilot

Task: Get yourself familiar with Copilot inline code and Copilot chat. Try out Slash commands

//help

together with Strg + Alt + Enter and ask Copilot some questions about code / coding.ch

Scenario 1️⃣: Create interest calculator without compound interest

Task: Use GitHub Copilot chat to create an interest calculator in C++ (.cpp file). Keep in mind that you want to import this module later in your unittest file. Hint: If you're unsure about the formula for interest without compound, ask Copilot for assistance.

Scenario 2️⃣: Create interest calculator with compound interest

Task: Use GitHub Copilot to create an interest calculator with compound interest. But this time, use the comment or online chat function to ask Copilot for assistance.

Scenario 3️⃣: Build simple unittest

Task: Build a simple unittest for the interest calculator. Test different scenarios such as:

• Calculating interest for different principal amounts
• Calculating interest for different interest rates
• Checking that the calculated interest matches the expected result

⚠️SPOILER ALERT: Here are some sample prompts if you get stuck!
