C编译器在功能之前需要标识符

问题描述

我一直试图在c中编写一个minesweeper函数，该函数每次遇到空白时都会扩展块的区域，但是每次尝试构建时，我都会不断收到错误...\Desktop\Test\main.c|38|error: expected ';',',' or ')' before 'int'，尽管该函数似乎非常适合我。我的代码在这里：

#include <windows.h> /* for HANDLE type,and console functions */
#include <stdio.h> /* standard input/output */
#include <stdlib.h> /* included for rand */

#define WIDTH 30
#define HEIGHT 30
#define BOMBS 90

HANDLE wHnd; /* write (output) handle */
HANDLE rHnd; /* read (input handle */

void SetGrid(int grid[WIDTH][HEIGHT])
{
    int bomb[2] = { abs(rand() % WIDTH-1) + 1,abs(rand() % HEIGHT-1) + 1 };

    for (int i = 0; i < BOMBS; i++)
    {
        while (grid[bomb[0]][bomb[1]] < -1 || bomb[0] == 0 || bomb[1] == 0 || bomb[0] >= WIDTH-1 || bomb[1] >= HEIGHT-1)
        {
            bomb[0] = abs(rand() % WIDTH-1) + 1;
            bomb[1] = abs(rand() % HEIGHT-1) + 1;
        }

        grid[bomb[0]][bomb[1]] = -9;

        grid[bomb[0] + 1][bomb[1] + 1]++;
        grid[bomb[0] + 1][bomb[1]    ]++;
        grid[bomb[0]    ][bomb[1] + 1]++;
        grid[bomb[0] - 1][bomb[1] + 1]++;
        grid[bomb[0]    ][bomb[1] - 1]++;
        grid[bomb[0] + 1][bomb[1] - 1]++;
        grid[bomb[0] - 1][bomb[1] - 1]++;
        grid[bomb[0] - 1][bomb[1]    ]++;
    }
}

void ExpandGrid(int fullGrid[WIDTH][HEIGHT],int knownGrid[WIDTH][HEIGHT] int blankPos[2])
{
    int neighbors[8][2] = {{0,1},{1,0},{0,-1},{-1,-1}};
    int curTile[2];

    for(int blck = 0; blck < 8; ++blck)
    {
        curTile[0] = blankPos[0]+neighbors[blck][0];
        curTile[1] = blankPos[1]+neighbors[blck][1];

        if(fullGrid[curTile[0],curTile[1]] == 0)
        {
            knownGrid[curTile[0],curTile[1]] == 1;
            ExpandGrid(fullGrid,knownGrid,curTile);
        }
        else if(fullGrid[curTile[0],curTile[1]] > 0) {knownGrid[curTile[0],curTile[1]] == 1};
    }
}

int main(void)
{
    /* there will be two grids,a known grid and a full grid.
       for the full grid,a zero at a position [x][y] will indicate a blank space.
       a positive will be the tiles number,and a negative will be a bomb.

       for the known grid,a zero at space [x][y] will indicate an unknown block.
       while a 1 will indicate it is uncovered.
    */

    srand(time(0));

    SMALL_RECT windowSize = { 0,WIDTH - 1,HEIGHT - 1 };

    //COORD bufferSize = { WIDTH,HEIGHT };

    COORD characterBufferSize = { WIDTH,HEIGHT };
    COORD characterPosition = { 0,0 };
    SMALL_RECT consoleWriteArea = { 0,HEIGHT - 1 };

    CHAR_INFO consoleBuffer[WIDTH][HEIGHT];

    wHnd = GetStdHandle(STD_OUTPUT_HANDLE);
    rHnd = GetStdHandle(STD_INPUT_HANDLE);

    SetConsoleTitle("Minesweeper!");

    SetConsoleWindowInfo(wHnd,TRUE,&windowSize);
    //SetConsoleScreenBufferSize(wHnd,bufferSize);

    int startGrid[WIDTH][HEIGHT] = { 0 };
    int knownGrid[WIDTH][HEIGHT] = { 0 };
    SetGrid(startGrid);

    for (int x = 0; x < WIDTH; ++x)
    {
        for (int y = 0; y < HEIGHT; ++y)
        {
            if (startGrid[x][y] > 0)
            {
                consoleBuffer[x][y].Char.AsciiChar = '0' + startGrid[x][y];
                consoleBuffer[x][y].Attributes = FOREGROUND_GREEN | FOREGROUND_INTENSITY;
            }
            else
            {
                consoleBuffer[x][y].Char.AsciiChar = 'o';
                consoleBuffer[x][y].Attributes = (startGrid[x][y] < 0 ? FOREGROUND_RED : FOREGROUND_BLUE) | FOREGROUND_INTENSITY;
            }
        }
    }

    WriteConsoleOutputA(wHnd,consoleBuffer,characterBufferSize,characterPosition,&consoleWriteArea);

    getchar();
}

如果我是正确的话，通常只会在您忘记在上一行代码结尾时才会出现此错误，但在这里我认为并非如此。这是否与函数是递归的事实有关，还是与编译器有关？您可能会说，我对c很陌生。
