Golang Constants Programming Challenge

Introduction

This challenge aims to test your understanding of constants in Golang.

Skills Graph

Constants

The problem to be solved is to demonstrate the use of constants in Golang for character, string, boolean, and numeric values.

Requirements

The Challenge has the following requirements:

• Use the const keyword to declare a constant value.
• Constants should be of character, string, boolean, and numeric values.
• A constant statement can appear anywhere a var statement can.
• Demonstrate that constant expressions perform arithmetic with arbitrary precision.
• A numeric constant has no type until it's given one, such as by an explicit conversion.
• A number can be given a type by using it in a context that requires one, such as a variable assignment or function call.

Example

$ go run constant.go
constant
6e+11
600000000000
-0.28470407323754404

Summary

In this challenge, you learned how to declare and use constants in Golang. Constants can be of character, string, boolean, and numeric values. Constant expressions perform arithmetic with arbitrary precision. A numeric constant has no type until it's given one, such as by an explicit conversion.
