The Fibonacci example exits unexpectedly on windows.

[MadVikingGod]

Description

When running the Fibonacci example under windows after providing the first number the program exits with an error unexpected newline

PS C:\Users\Aaron\projects\opentelemetry-go\example\fib> go run .
What Fibonacci number would you like to know:
8
Fibonacci(8) = 21
What Fibonacci number would you like to know:
unexpected newline
exit status 1

Environment

• OS: windows Powershell (does not effect WSL, git bash, linux powershell)
• Architecture: x86-64
• Go Version:
  • go version go1.16 windows/amd64
  • go version go1.18.1 windows/amd64
• opentelemetry-go version: main, 68d538a

Steps To Reproduce

1. Use the configuration running in powershell
2. Run:

PS C:\Users\Aaron\projects\opentelemetry-go> cd .\example\fib
PS C:\Users\Aaron\projects\opentelemetry-go\example\fib> go run .
What Fibonacci number would you like to know:
8
Fibonacci(8) = 21
What Fibonacci number would you like to know:
unexpected newline
exit status 1

cd fib
4. See error: unexpected newline

Expected behavior

This should operate the same as linux, wsl, or git bash. Where it will prompt you for another number until you use ctrl+c.
