Mastering Go Constants: Configuration Values

Constants in Go are fundamental for representing fixed values that should not change during program execution. This challenge focuses on creating and utilizing constants effectively for application configuration, a common and crucial task in software development.

Problem Description

Your task is to define and use constants in Go to represent important configuration values for a simple application. This will involve declaring constants of different types and demonstrating how they can be referenced throughout your code.

What needs to be achieved:

1. Define several constants representing common configuration settings.
2. Use these constants in a simple Go program to simulate their application.

Key requirements:

• Declare constants for:
  • A string representing an API endpoint URL.
  • An integer representing a maximum retry count.
  • A boolean indicating whether debugging is enabled.
  • A floating-point number representing a default timeout duration in seconds.
• Print the values of these constants to the console.
• Ensure the constants are declared at the package level.

Expected behavior:

The program should compile and run without errors, printing the declared constant values to standard output.

Edge cases to consider:

• While this challenge doesn't involve dynamic input, understanding how constants provide stable defaults is key.

Examples

Example 1:

Input: (No direct input required for this challenge, focus is on code structure)

Output:
API Endpoint: https://api.example.com/v1
Max Retries: 5
Debugging Enabled: true
Default Timeout: 30.5

Explanation: The output displays the values of the defined constants as they would be used within an application.

Example 2:

Input: (Same as Example 1)

Output:
API Endpoint: https://api.example.com/v1
Max Retries: 5
Debugging Enabled: true
Default Timeout: 30.5

Explanation: This confirms that regardless of how the program is run (in this simple case), the constants hold their predefined values.

Constraints

• All constants must be declared using the const keyword.
• The constants should be of the types: string, int, bool, and float64.
• The solution must be a single Go file.
• The program should not rely on any external libraries beyond the standard fmt package.

Notes

• Consider using iota if you need to define a sequence of related constants, although it's not strictly required for this specific challenge.
• Think about naming conventions for constants in Go (e.g., ALL_CAPS_WITH_UNDERSCORES).
• The purpose of constants is to make your code more readable, maintainable, and less prone to "magic numbers" or hardcoded strings.
