'''Title Slide '''
|| Welcome to the Spoken Tutorial on '''Prompt Engineering'''. 
|- 
|| '''Slide 2'''

'''Learning Objectives'''
|| In this tutorial, we will learn about
* Prompt engineering
* Importance of context and background
* Few-shot prompting 
|- 
|| '''Slide 3'''

'''System Requirements'''
|| To record this tutorial, I am using 
* Ubuntu Linux OS version 22.04 
* Firefox web browser version 141.0.4
* Visual Studio Code version 1.100.3
|- 
|| '''Slide 4 '''

'''Pre-requisites '''
|| To follow this tutorial, learners should have basic knowledge of:
* Using internet, and
* Programming in C/C++ 
|-
|| '''Slide 5'''

'''Code files'''

The following code file is required to practice this tutorial.
# '''prompt-engineering.cpp'''

This file is provided in the Code Files link of this tutorial page.

'''What is Prompt Engineering?'''
|| Let us learn about Prompt engineering.
* It is a skill of writing and refining prompts for AI tools like ChatGPT.
* It means designing clear instructions, questions, or context.
* Good prompts guide the AI tool to give accurate, useful, or creative answers.
|- 
|| '''Highlight the address bar in Google Chrome'''
|| Open ChatGPT on any browser.
|- 
|| 
|| Let us give a prompt to ChatGPT.
|- 
|| '''Highlight''' 

'''Ask anything in the middle of the page'''

'''Type:''' You are a C++ tutor.

Explain the difference between function overloading and function overriding in C++ with examples. Press Enter. 
|| You are a C++ tutor. Explain the difference between function overloading and function overriding in C++ with examples. Press Enter. 
|- 
|| '''Highlight the generated response in the chat window'''
|| ChatGPT first defines function overloading, followed by an example. 

Similarly, for function overriding. 

Then tabulates the differences between the two. 

Note that the content of the response may differ at your end, even with the same prompt. 
|- 
|| '''Highlight compile-time polymorphism in the generated response'''
|| Suppose I am unfamiliar with compile-time polymorphism. 

I can ask ChatGPT to provide further explanation. 

Highlight this term. 

Observe that an option of “Ask ChatGPT” appears. 

Click this option and type your query.

I will type, explain this term, and press Enter. 

ChatGPT now explains compile-time polymorphism. 
|- 
|| '''Highlight some terms in the generated response such that the Ask ChatGPT option appears '''
|| “Ask ChatGPT” is a built-in feature of ChatGPT’s web app. 

Think of it like a shortcut for quickly asking “What does this mean?” 
|- 
|| 
|| Let us try another prompt.
|- 
|| 
|| I am a first-year Computer Science student, and I know the concepts of variables and functions.

I want ChatGPT to explain references in C++. 
|- 
|| '''Click New Chat '''
|| Click on New chat to open a new chat. 
|- 
|| '''Type: '''Explain the concept of references in C++ to a first-year CS student who only knows variables and functions. Press Enter.

'''Highlight the few lines of response'''
|| Type the following

And, press Enter.

Observe the response.

ChatGPT explains the concept of references in C++. 
|- 
|| 
|| Next, I want to teach the concept of dangling pointers in C with some funny analogy. 
|- 
|| '''Click New chat'''

'''Type: '''Explain the concept of dangling pointers in C in a way that a beginner can understand, using a funny or relatable real-life analogy.
|| Click New chat to start a new conversation.

In the new chat, type the following. 

And, press Enter. 
|- 
|| '''Highlight the Funny analogy in the generated response'''

'''Scroll and show'''

'''Cursor on previous chat'''
|| See how ChatGPT adds a funny analogy in its response.

All my previous chats appear under Chats in the sidebar.

I can click on any of them to open and continue that conversation.
|- 
|| 
|| Let us now learn about few-shot prompting. 
|- 
|| '''Slide 7'''

'''Few-shot Prompting '''
|| If we give ChatGPT a few inputs with examples, it will resolve the issues.

This technique helps the tool recognize patterns and apply them to similar unseen problems.
|- 
|| '''Show the code in the visual studio code editor.'''
|| Let us try out a few-shot prompt with an example. 


I have a C++ code, and I want ChatGPT to identify the error in a particular format. 
|- 
|| Type

'''Identify the error in the following C++ code.'''

'''Code:'''

'''int main() {'''

'''int a = "hello";'''

'''return 0;'''

'''}'''

'''Error:'''

'''Assigning a string literal to an int variable is invalid.'''


'''Code:'''

'''int main() {'''

'''cout << "Hello";'''

'''return 0'''

'''}'''

'''Error:'''

'''Missing semicolon after return 0.'''


'''Code:'''

'''int main() {'''

'''int arr[3] = {1, 2, 3, 4};'''

'''return 0;'''

'''}'''

'''Error:'''
|| Go to ChatGPT and start a new chat. 

Type the code at the prompt: 

And press Enter. 
|- 
|| '''Highlight Error: in the generated response '''
|| Observe that ChatGPT prints the error with Error semicolon.

Then the error message, followed by an explanation. 
|- 
|| 
|| More information on prompt engineering and 
few-shot prompting, is provided in the Additional Reading Material available on this tutorial page.
|-
|| '''Slide 8'''

'''Summary'''

In this tutorial, we have learnt
* Prompt Engineering
* Importance of Context and Background 
* Few-shot Prompting 
|| With this, we come to the end of this tutorial. 

Let us summarise.
|- 
|| '''Slide 9'''

'''Assignment '''

Give ChatGPT the same programming question using two scenarios: 
# Without role or context, and 
# With role and context. 

Compare how the answers differ.
|| As an assignment,
