The Prompt
Create a detailed and clear plan to build an age calculator app.
**Include the following details:**
1. Define the purpose of the age calculator app
(e.g., calculate a person’s exact age in years, months, days).
2. Specify the input requirements from the user
(e.g., date of birth in a specific format).
3. List the key functionalities
(e.g., validate input, compute age accurately considering leap years, display output clearly).
4. Suggest an appropriate technology stack or programming language
for building the app.
5. Provide a basic outline of the app’s user interface and user experience.
6. Describe how to test the app
to ensure accuracy and reliability.
**# Steps**
– Understand the exact features and requirements of the age calculator.
– Gather user input correctly and validate it.
– Implement the logic to calculate the difference between the current date and the input date.
– Handle edge cases like leap years and invalid inputs.
– Design a simple UI that clearly shows the resulting age.
– Test extensively under varying input scenarios.
**# Output Format**
Provide a structured plan/documentation including all the points above in clear sections with bullet points or numbered lists for easy readability.
