本Delphi代码实现一段字符的分类统计，可分别统计出字符串中的英文字符数量和中文汉字数量，中文和英文在计算机中是区别对待的，因此本代码抓住这一特点，实现字符的分类统计，具体代码：

unit Unit1;
interface
uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls;
type
  TForm1 = class(TForm)
    Memo1: TMemo;
    Label1: TLabel;
    Label2: TLabel;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;
var
  Form1: TForm1;
implementation
{$R *.DFM}
procedure TForm1.Button1Click(Sender: TObject);
var
  s:string;
  i,e,c:integer;
begin
  s:=memo1.text;
  e:=0;c:=0;
  for i:=1 to length(s) do
  begin
    if (ord(s[i])>=33)and(ord(s[i])<=126) then
    begin
      inc(e);
      label1.caption:='英文个数：'+inttostr(e);
    end
    else if (ord(s[i])>=127) then
    begin
      inc(c);
      label2.caption:='中文个数：'+inttostr(c div 2);
    end;
  end;
end;
end.
