Pascal：不兼容的类型：得到“LONGINT”预期的“CHAR”

Question

我不断收到“98 / 39 comp1_~1.pas 错误：类型不兼容：“LONGINT”应为“CHAR”。这是关于第 6 行。请提供帮助。

Function RollBowlDie(VirtualDiceGame : Boolean) : Integer;
  Var
    BowlDieResult : Char;
  Begin
      If VirtualDiceGame
      Then BowlDieResult := Random(6) + 1
      Else
        Begin
        Repeat
          Writeln('Please roll the bowling die and then enter your result.');
          Writeln;
          Writeln('Enter 1 if the result is a 1');
          Writeln('Enter 2 if the result is a 2');
          Writeln('Enter 3 if the result is a 4');
          Writeln('Enter 4 if the result is a 6');
          Writeln('Enter 5 if the result is a 0');
          Writeln('Enter 6 if the result is OUT');
          Writeln;
          Write('Result: ');
          Readln(BowlDieResult);
          If not (BowlDieResult in ['1'..'6'])
          Then
              Begin
              Writeln;
              Writeln('That was not one of the allowed options. Please try agai:');
              End;
          Until BowlDieResult in ['1'..'6'];
        End;
RollBowlDie := Ord(BowlDieResult)  - Ord('0');
  End;

Answer 1

那么问题出在哪里呢？

BowlDieResult 是一个 char，但您要为其分配一个 longint。

我的帕斯卡有点生锈了，但是试试

 BowlDieResult := chr(49 + Random(6));
