The Best Guide to Prompt ChatGPT to Write Code Completely

Do you really know the way to prompt ChatGPT to write code perfectly? As AI continues to advance, language models such as ChatGPT have become increasingly capable of assisting in various tasks, especially code writing. In detail, prompting ChatGPT to generate code can be a powerful tool for developers, enabling them to automate repetitive tasks and explore new programming possibilities. But not all of us know the way to prompt ChatGPT, some users are still struggling to have the desired results. In this blog, we will provide a comprehensive guide on effectively prompting ChatGPT to write code, maximizing its potential while mitigating challenges and biases.

The Best Guide to Prompt ChatGPT to Write Code

Challenges and Limitations of Code Generation with ChatGPT

  • Lack of context awareness: ChatGPT generates code based on the input provided, but it doesn’t have a deep understanding of the broader context or project-specific requirements. Therefore, it may generate code that works but doesn’t align with the overall architecture or best practices of the project.
  • Limited knowledge of recent updates: According to our recent research, we found that almost ChatGPT’s knowledge is based on information available up until September 2021. As a result, it may not be aware of the latest language updates, libraries, or frameworks released after that date. Hence, it might not provide the most up-to-date or optimized solutions for specific programming tasks.
  • Difficulty with complex logic: While ChatGPT can handle simple programming tasks, it may struggle with more complex logic or intricate algorithms. It might generate code that is syntactically correct but inefficient or suboptimal for specific use cases.
  • Lack of error handling: ChatGPT primarily focuses on generating code but may not provide robust error handling or exception management. It’s essential to manually review and enhance the generated code to handle edge cases, error scenarios, and input validation.

Code generation with ChatGPT is considered a good tool for writing code, nevertheless, in case we do not understand and know how to write a prompt, it can lead to various challenges and limitations.

So now, the question is: “How can we Prompt ChatGPT to Write Code Exactly?” 

It can be said that using ChatGPT to write code is straightforward. You must provide a prompt or a description of the code you want to generate. Accordingly, ChatGPT will then analyze the prompt and create a code snippet matching the description. Here’s a step-by-step guide on how to use ChatGPT to write code:

Step 1: Select a programming language

ChatGPT can generate code in multiple programming languages such as Python, Java, JavaScript, and more. You must specify the programming language you want it to use when generating the code. 

Some Programming Languages

Step 2: Provide ChatGPT with a Prompt

The ChatGPT prompt should describe the code you wish to generate. It should be written in natural language and clearly state the desired functionality of the code snippet. For instance, if you want to generate a code snippet that sorts an array of integers, your prompt could be “Create a function that arranges an array of integers in ascending order.”

Step 3: Generate a Code

Break down your prompts and keep them simple

One of the key aspects of prompting ChatGPT to write code is to break down the prompts into simple and concise statements. Complex prompts need to be clarified for the model and lead to accurate or irrelevant code generation. Instead, focus on providing clear instructions, specifying the desired outcome, and straightforwardly presenting the problem. This helps ChatGPT to understand and respond accurately to the given prompt.

For example, instead of requesting it to “write a program to calculate the Fibonacci sequence,” you have the option to divide it into smaller and more simple prompts, such as “write a function to calculate the Fibonacci number for a given index.”

Example of Prompting ChatGPT to Write CodeAssign a role for ChatGPT

Giving ChatGPT a specific persona can help it understand what you want. For example, you could assign it the role of a “world-class programmer” or a “software engineer with 10 years of experience”. This will help ChapGPT to generate code that is more consistent with the persona you have assigned to it.

Update the basics 

No matter how specific your prompts are, language can still be ambiguous. This means you still need to have some understanding of how to steer the chatbot and what results you expect to see. For example, if you want ChatGPT to write a function to calculate the Fibonacci sequence, you should understand the basic algorithm for calculating the Fibonacci sequence. This will help you to communicate your requirements to ChatGPT more effectively.


To conclude, prompting ChatGPT to write code requires a thoughtful approach to maximize its effectiveness. By the following guide, you can guide the language model to generate accurate and relevant code. Remember to provide clear instructions, context, and constraints to improve the quality of the output. With these guidelines in mind, you can harness the power of ChatGPT, making your coding experience more productive and efficient.
