这个函数中的某些东西使我的程序崩溃了！

Question

你好，当我的程序开始执行 switch 语句的 case N 代码时，它崩溃了。我不知道为什么。有人愿意看一下吗？

代码：（我怀疑问题发生在 switch 语句的 case N 的某个地方）

#include "header.h"

void findSeats(int& FC_Row, int& FC_Col, int& EconRow, int& EconCol, int& ticketNum, int& rowNum, char& ticketType, char& seatType, int airplane[][6])
{
    int aisle,  col;
    char letterCol;

    if (ticketType = 'F')
        {
            switch (seatType)
            {
                case 'W':
                if (airplane[rowNum - 1][0] == 0)
                    {
                    airplane[rowNum - 1][0] = 1;
                    cout << "Your seat is " << (rowNum) <<  "A" << endl;
                    }
                else if (airplane[rowNum-1][FC_Col - 1] == 0)
                    {
                    airplane[rowNum - 1][FC_Col] = 1;
                    cout << "Your seat is " << (rowNum) <<  "D" << endl;

            }
        }
}

删除对自身的函数调用解决了问题。

我怀疑 rownum 是 0

负索引不好。
