【实践】delphi简易成绩表

lgd0722

二维数组的实践结果，delphi中比较容易搞混数组的下标是行还是列。
unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, Grids, StdCtrls;

type
  TForm1 = class(TForm)
    strngrdtable1: TStringGrid;
    btn1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure btn1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
  strngrdtable1.Cells[0,1]:= '小明';
  strngrdtable1.Cells[0,2]:= '小红';
  strngrdtable1.Cells[1,0]:= '语文';
  strngrdtable1.Cells[2,0]:= '数学';
  strngrdtable1.Cells[3,0]:= '英语';
  strngrdtable1.Cells[4,0]:= '总成绩';
end;

procedure TForm1.btn1Click(Sender: TObject);
var
  i,j: Integer;
  cjb: array[1..4] of array [1..2] of Integer;

begin
  for i:= 1 to 2 do
  begin
    cjb[4,i]:= 0;
    begin
      for j:= 1 to 3 do
        begin
          cjb[j]:= StrToInt(strngrdtable1.Cells[j,i]);
          cjb[4]:= cjb[4] + cjb[j];
        end;
    end;
  end;

  strngrdtable1.Cells[4,1]:= IntToStr(cjb[4][1]);
  strngrdtable1.Cells[4,2]:= IntToStr(cjb[4][2]);
end;

end.
