Question

这是带有问题的代码：

#ifndef WEAPONS_H_INCLUDED
#define WEAPONS_H_INCLUDED
#include "Battleship header.h"

void Player::torpedo(string enemyEvtTracker[][10], string myhitboard[][10])
{
    string bcn; //board column number
    cout << "Enter board column number (1-9): "; cin >> bcn; flush();
    if(bcn!="1"&&bcn!="2"&&bcn!="3"&&bcn!="4"&&bcn!="5"&&bcn!="6"&&bcn!="7"&&bcn!="8"&&bcn!="9")
    {cout <<endl<< "That is not a valid number.";}
    return;
}



#endif // WEAPONS_H_INCLUDED

这是类Player：

Answer 1

Player::torpedo(string enemyEvtTracker[10][10], string myhitboard[10][10])
{
  //..
}

这是成员函数的定义。声明在哪里？

我的猜测是，在声明中你没有提到数组的大小，就像你在定义中所做的那样。看来你写的只是enemyEvtTracker [][]？请参阅Player类的定义，并验证您如何在其中声明torpedo成员函数。

多维数组故障（边界）
