Can you please make a video explaining how to declare arrays in a class, and how they would be implemented into the constructor create.

[ameesharanchhod]

can you please help with adding columns into a string grid and populating it from a 2D Array?

var iX, iY : integer;
iSum : real;
begin

for iX := 1 to 6 do
begin
iSum := 0 ;
StringGrid1.Cells[iX, 0] := IntToStr(iX);
for iY := 1 to 4 do
begin
StringGrid1.Cells[0, iY] := IntToStr(iY);
StringGrid1.Cells[iX, iY] := IntToStr(random(45) + 14 );
iSum := iSum + StrToInt(StringGrid1.Cells[iX, iY]) ;
end;
StringGrid1.Cells[iX, 5] := FloatToStr (iSum / 4);
end;
StringGrid1.Cells[0, 5] := 'Avg :';
