C++ Sample 1:

  #include "clipper2/clipper.h"
  ...
  using namespace Clipper2Lib;
  int main()
  {
    Paths64 subject, clip, solution;
    subject.push_back(MakePath({100, 50, 10, 79, 65, 2, 65, 98, 10, 21}));
    clip.push_back(MakePath({98, 63, 4, 68, 77, 8, 52, 100, 19, 12}));
    solution = Intersect(subject, clip, FillRule::NonZero);    
  }

C# Sample 1:

  ...
  using Clipper2Lib;	
  ...
  static void Main(string[] args)
  {
    Paths64 subj = new Paths64();
    Paths64 clip = new Paths64();
    subj.Add(Clipper.MakePath(new int[] { 
      100, 50, 10, 79, 65, 2, 65, 98, 10, 21 }));
    clip.Add(Clipper.MakePath(new int[] {

    Paths64 solution = Clipper.Intersect(subj, clip, FillRule.NonZero);
  }

Delphi Sample 1:

  uses
    Clipper, Clipper.Core;
  	
  var 
    subject, clip, solution: TPaths64;
  begin
    SetLength(subject, 1);
    subject[0] := MakePath([100, 50, 10, 79, 65, 2, 65, 98, 10, 21]);

    solution := Intersect( subject, clip, frNonZero);
    
    //DrawPolygons

C++ Sample 2:

  #include "clipper2/clipper.h"
  ...
  using namespace Clipper2Lib;
    
  int main()

    Paths64 clip;

    //get the intersection
    Paths64 solution = Intersect(subject, clip, FillRule::EvenOdd);
    
    //DrawPolygons    
  }
