PASCAL字符串到数组 [英] PASCAL string to array

问题描述

帕斯卡，我如何转动（读取）诸如数字 21354561321535613的字符串成数字并将其存储在数组？

Pascal, How can i turn (read) a string of numbers like for example '21354561321535613' into digits and stock them in an array ?

推荐答案

您可以通过减去序号'0'<轻松地将数字转换为整数/ code>。循环执行此操作，每个数字都有一个整数：

You can easily turn a digit into an integer by subtracting the ordinal value of '0'. Do this in a loop and you have an integer for each digit:

var
  S: string;
  A: array of Integer;
  I, Len: Integer;
begin
  S := '21354561321535613';
  Len := Length(S);

  { Reserve Len Integers. }
  SetLength(A, Len);

  { Convert each digit into an integer: }
  for I := 1 to Len do
    A[I - 1] := Ord(S[I]) - Ord('0'); { [I - 1] because array is zero-based. }
end;
