Description

Currently, the consumer_example.go file lacks error handling for the SubscribeTopics function call. This makes the application vulnerable to potential failures during topic subscription. To ensure robustness and proper error handling, we need to add error checking and handling for this function call.

How to reproduce

N/A

Proposed Solution

====================

Add error handling logic after the SubscribeTopics function call in the main function of consumer_example.go. Specifically, check for errors returned by the function call and exit the program with an error message if subscription fails.

Additional Information

This issue is critical for ensuring the reliability of the Kafka consumer application. Proper error handling during topic subscription is essential for smooth operation in production environments.
