Question

当我尝试编译我正在处理的一些源代码时，我收到此错误。我对编程非常陌生，因为某些原因，数组一直给我带来困难：

airline2.cpp:9:84: error: too many initializers for ‘char [4]’
   char array_seats[][4] = {{'1', '2', '3', '4', '5', '6', '7'},{'A', 'B', 'C', 'D'}};

这是我的源代码：

#include <iostream>
using namespace std;

int main()
{
  char row, letter, answer;
  int letter2;

  char array_seats[][4] = {{'1', '2', '3', '4', '5', '6', '7'},{'A', 'B', 'C', 'D'}};

  for (int row = 0; row <= 6; row++)
    {
      for (int letter = 0; letter <= 4; letter++)
    {
      cout << array_seats[row][letter] << " ";
    }
      cout << endl;
    }

  do
    {
      cout << "Enter your desired seat row:\n";
      cin >> row;
      cout << "Enter a seat letter:\n";
      cin >> letter;

      if(letter == 'A' || letter == 'a')
    letter2 = 1;
      else if(letter == 'B' || letter == 'b')
    letter2 = 2;
      else if(letter == 'C' || letter == 'c')
    letter2 = 3;
      else if(letter == 'D' || letter == 'd')
    letter2 = 4;

      if(array_seats[row-1][letter2] == 'X')
    cout << "Sorry, this seat is taken.\n" << endl;

      else
    {
      array_seats[row-1][letter2] = 'X';
      cout << "Seat reservation successful.\n" << endl;
    }

      for (int row = 0; row <= 6; row++)
    {
      for (int letter = 0; letter <= 4; letter++)
        {
          cout << array_seats[row][letter] << " ";
        }
      cout << endl;
    }

      cout << "Would you like to try again? (Y/N)\n";
      cin >> answer;

    }while (answer == 'Y' || answer == 'y');

  cout << "Have a good flight!\n";

  return 0;

}

我尝试将错误设置为5并在结尾添加'\ 0'，但似乎没有任何效果。有什么帮助吗？

Answer 1

char array_seats[][4] = {{'1', '2', '3', '4', '5', '6', '7'},{'A', 'B', 'C', 'D'}};

{'1'，'2'，'3'，'4'，'5'，'6'，'7'}超过4

Answer 2

您尝试初始化2D阵列的方式存在语法错误。

  char array_seats[][4] = {{'1', '2', '3', '4', '5', '6', '7'},{'A', 'B', 'C', 'D'}};

上述行意味着每行将有4个元素。如果你看到第一行，它有7个元素，{'1'，'2'，'3'，'4'，'5'，'6'，'7'}。将此值减少为4个元素，编译错误将消失。所以你的array_seats现在有2行4列

注意：执行上述操作将解决编译错误，但您的程序会遇到严重的运行时错误。特别是当您尝试访问array_seats [2] [0]等时

C ++：为'char [4]'数组错误获取太多初始值设定项
