Hello, everyone. I'm writing a program which finds all possible side lengths of quadrangle to match specified area. I've checked the code - everything works, except the part (it's in bold), where the program has to write matching pair of quadrangle side lengths.
program Area; var x, y, S, n: real; begin WriteLn('Enter quadrangle area:'); ReadLn(S); WriteLn('Enter accuracy:'); ReadLn(n); x:=n; y:=n; WriteLn; WriteLn('Calculating possible lenghts of quadrangle sides...'); While (xy<>S) and (y<=(S/n)) and (x<=S) do begin If x+n<=S then x:=x+n else begin x:=n; y:=y+n; End; ** If xy=S then WriteLn(x2,' ; ', y2);** End; WriteLn; WriteLn('Calculation has been finished.'); ReadLn; end.
What's wrong there? Could be a compiler bug or something other?
