When a function is called, the computer must "remember" the place it was called from... so that it can return to that location with the result once the call is complete. Typically, this information is saved on the call stack... For tail calls, there is no need to remember the caller...
https://en.wikipedia.org/wiki/Tail_call
Some interpreters (and compilers) eliminate the stack frame creation and destruction work when they recognize tail recursion.
Adding a "HaddleyOffice365.dotnet-factorial" package to NuGet.org.
NuGet is the package manager for .NET.
Start by creating a dotnet-factorial repository in the https://github.com/HaddleyOffice365 profile.
New repository will be named dotnet-factorial
Publish to GitHub
Open in Visual Studio Code
Create a dotnet solution
$ dotnet new sln
Create a class library project and add the new class library project to the solution
$ dotnet new classlib -o dotnet-factorial
$ dotnet sln add ./dotnet-factorial/dotnet-factorial.csproj
Create a test project and add the new test project to the solution
$ dotnet new mstest -o unittests
$ dotnet sln add ./unittests/unittests.csproj
At a reference from the unit tests project to the factorial project.
$ dotnet add ./unittests/unittests.csproj reference ./dotnet-factorial/dotnet-factorial.csproj
Add a .gitignore file to the unit tests project directory and to the factorial project directory.
$ cd dotnet-factorial
$ dotnet new gitignore
$ cd ../unittests
$ dotnet new gitignore
$ cd ..
new solution, new classlib project and new mstest project
Rename the generated UnitTest1 class to "UnitTests"
Copy Class1 class and rename to "recursivefunctions.cs"
Rename the generated Class1 class to "iterativefunctions"
Update the file contents:
UnitTests.cs
iterativefunctions.cs
recursivefunctions.cs
use "dotnet test" to run the unit test locally on the development machine.
$ dotnet test
dotnet test
Commit updates to the repository.
