What is 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.

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.

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.

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.

Think of it like a shortcut for quickly asking “What does this mean?”

I want ChatGPT to explain references in C++.

Highlight the few lines of response

And, press Enter.

Observe the response.

ChatGPT explains the concept of references in C++.

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.

In the new chat, type the following.

And, press Enter.

Scroll and show

Cursor on previous chat

All my previous chats appear under Chats in the sidebar.

I can click on any of them to open and continue that conversation.

Few-shot Prompting

This technique helps the tool recognize patterns and apply them to similar unseen problems.

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

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:

Type the code at the prompt:

And press Enter.

Then the error message, followed by an explanation.

few-shot prompting, is provided in the Additional Reading Material available on this tutorial page.

Summary

In this tutorial, we have learnt

• Prompt Engineering
• Importance of Context and Background
• Few-shot Prompting

Let us summarise.

Assignment

Give ChatGPT the same programming question using two scenarios:

1. Without role or context, and
2. With role and context.

Compare how the answers differ.
