Scenario: You are working on an application that tracks user ages. The ages range from 0 to 150. What would you choose: int, short, or byte? Explain your choice.

Answer:

The most appropriate choice here is short. The reason is that int is larger than necessary for storing ages in this range (0 to 150), and byte only supports values from -128 to 127, so it won’t work for ages up to 150. A short can hold values between -32,768 and 32,767, making it both memory-efficient and capable of handling the required range.

short age = 25; // Appropriate data type for ages in the range of 0-150
