运行时检查失败#2 - 变量“位置”周围的堆栈已损坏

Question

我在返回结构时遇到问题。它说运行时检查失败#2 - 变量“位置”周围的堆栈已损坏，我不知道为什么。我必须在今晚之前完成这项工作才能继续该项目的其余部分。如果你知道的话请帮忙。谢谢 ：）

struct Position

Answer 1

在初始循环中，您分别使用索引 1 到 5 和 1 到 2 为 SrcDstScore 和 pieceColor 建立索引。这些应该是索引 0 到 4 和 0 到 1。

同样的情况也适用于这一行及其后面的三行：

positions.SrcDstScore[counter][1]= Row;

并且在您有 positions.SrcDstScore[counter][5]，应该是 ...[4]

Answer 2

 positions.pieceColor[t][1]= ' ';
 positions.pieceColor[t][2]= ' ';

它应该是 -

 positions.pieceColor[t][0]= ' ';
 positions.pieceColor[t][1]= ' ';  // Array index starts from 0 to numElements - 1.

并且与 Position::SrcDstScore 的情况也相同。数组索引从0开始到4。

Answer 3

如果变量 theBoard 是一个 2D 数组或指向 Piece 的 2D 数组的指针，其尺寸为 8 * 8（对于棋盘），则该函数声明应如下所示：

Position EvaluateMoves(Piece (*theBoard)[8])  // 1st way
Position EvaluateMoves(Piece theBoard[][8])  // 2nd(a) way
Position EvaluateMoves(Piece theBoard[8][8])  // 2nd(b) way
Position EvaluateMoves(Piece (&theBoard)[8][8])  // 3rd way, preferred if theBoard is an array
