'[' 标记前的预期不合格 ID

Expected unqualified-id before '[' token

我知道这个错误一般是语法错误,但我似乎找不到这段代码有什么问题。谁能帮我指出来?以下是我遇到的错误:

deli.cc:10:7: error: expected unqualified-id before ‘[’ token int [] myCashierNums; ^ deli.cc:11:7: error: expected unqualified-id before ‘[’ token int [] myOrderNums; ^

这是我在 Ubuntu 14.04 64 位上使用 g++ 编译的程序。

#include <iostream>
#include <stdlib.h>

using namespace std;

class SandwichBoard {
  //private:
    int myMaxOrders;
    int [] myCashierNums;
    int [] myOrderNums;

  //public:
    SandwichBoard (int maxOrders) {
      myMaxOrders = maxOrders;
      myCashierNums = new int [maxOrders];
      myOrderNums = new int [maxOrders];

      // All values initialized to -1
      for (int i = 0; i < maxOrders; i++){
        myCashierNums[i] = -1;
        myOrderNums[i] = -1;
      }
    }

    // For debugging purposes
    void printMyOrders() {
      for (int i = 0; i < maxOrders; i++){
        cout << "Cashier " << myCashierNums[i] << ", ";
        cout << "Order " << myOrderNums[i] << endl;
      }
    }

    int getMaxOrders () { return myMaxOrders; }

};

void cashier(void *in) {

}

void sandwich_maker(void *in) {

}

int main(int argc, char *argv[]) {

}

这是 C++,不是 Java! 像这样声明数组:

int myCashierNums[1000];
int myOrderNums[1000];

请注意,C++ 中的数组在编译时必须有一个大小。在上面的例子中,它是 1000.

修改:

int myMaxOrders;
int* myCashierNums;
int* myOrderNums;

添加:

~SandwichBoard() {
    if (myMaxOrders) {
       delete [] myCashierNums;
       delete [] myOrderNums;
    }
}
