Question

我在main之前声明了结构：

struct roomData
{
  float widthFeet, widthInch;
  float lengthFeet, lengthInch;
  char roomName[100];
  int roomNumberOfType;
  char roomType[6]; //char of room type
  int roomStock[101][6]; //for storing each room stock types
  int roomHasStock; //if the room has a stock avaliable
  int roomStockCount; //how many stocks the room has
  float area;  // sq ft
  float rentalRate;
  float profitsPerRoom;
  float netProfit;
  float grossProfit;
};

在main中，我用这个声明结构：

int main(void)
{
struct roomData rooms[MAXROOMS+1] = {0}; //struct for rooms(+1 for temp swapping in sorts)
}

稍后我将struct和一些其他变量传递给main中使用此代码的函数：

        fillRoomData(n, x, array, rooms, 1);

，fillRoomData函数是这样的：

    void fillRoomData(int n, int x, struct fileInput array[300], struct roomData rooms[MAXROOMS], int check)//NEED TO ERROR CHECK
{
    if(check == 1) //for stock values in room
    {
        char * word4; //for strTok
        word4 = strtok(array[n].input," "); //stockType
        rooms[x].roomStock[a][0] = atoi(word4); //sores stock number
        word4 = strtok(NULL, " "); //stockCount
        rooms[x].roomStock[a][1] = atoi(word4); //sores stock inventory
....

}

这是我在rdb之后从GCC获得的错误

    1420                rooms[x].roomStock[a][b] = atoi(word4); //stores

非常感谢所有人的帮助！

尝试将您的主页更改为：

struct roomData rooms[MAXROOMS+1];

结构中的2D Int数组 - C.
