Interfaces

The problem is to implement an interface in Go, we just need to implement all the methods in the interface. Here we implement geometry on rects and circles.

Requirements

• Implement an interface in Go.
• Implement all the methods in the interface.
• Use a generic measure function to work on any geometry.
• Use instances of circle and rect structs as arguments to measure.

Example

$ go run interfaces.go
{3 4}
12
14
{5}
78.53981633974483
31.41592653589793

Summary

This challenge is about implementing an interface in Go. We implemented the geometry interface on rects and circles and used a generic measure function to work on any geometry.
