error: invalid types ‘const bool[int]’ for array subscript

Question

有人可以帮助我吗？我不知道我必须改变什么。我想创建一个二维网格和一些其他东西。

这是我的代码中最重要的部分。

#include <ncurses.h>

bool cells;
const MAX_GRID_SIZE;

//_________________________________________________
void initializeGame() {
  initscr();
  cbreak();
  noecho();
  curs_set(false);
  nodelay(stdscr, true);
  keypad(stdscr, true);
  mousemask(ALL_MOUSE_EVENTS, NULL);

  // Cells (0 = false, 1 = true).
  MAX_GRID_SIZE = 500
  cells[MAX_GRID_SIZE][MAX_GRID_SIZE] = { 0 };
}
//_________________________________________________
void showState() {
  while (true) {
    MEVENT event;
    int key = getch();
    if (key == KEY_MOUSE) {
      if (getmouse(&event) == OK && (event.bstate & BUTTON1_CLICKED)) {
        int x = event.x;
        int y = event.y;
        mvprintw(0, 0, "Mouse clicked at %d, %d\n", x, y);
        cells[x][y] = !cells[x][y];
        if (cells[x][y] == true) { attron(A_REVERSE); }
        mvprintw(y, x, " ");
        attroff(A_REVERSE);
        refresh();
      }
    }
  }

  // Clean up.
  endwin();
}

如果 cells 是一个二维数组，那么声明它：

const size_t MAX_GRID_SIZE = 500;
bool cells[MAX_GRID_SIZE][MAX_GRID_SIZE] = { 0 };
