C++ <；无法读取内存>；在使用fstream时

所以我一直试图打开我创建的一个文件，但当我试图打开我的文件时，我总是遇到一个错误。 下面是调试器所说的：

std::basic_ios<char,std::char_traits<char> > = <Unable to read memory>

---

您是否尝试取出第二个

余额文件。打开
对账单

我可能还会包括一个控制语句，如
if（balanceFile）
，这样您就知道您正在读取良好的数据。如果使用-g编译，是否会得到错误所在的行号？
一些有用的东西：

决定是保持文件打开并仅打开一次，还是多次打开和关闭并每次关闭

修正“balanceiFile”的拼写（为什么要编译？）

存储找到的行数，并检查它是否不超过数组的长度

检查请求的行数是否小于或等于找到的行数

int convert(string balance, int lineno){ // Funciton to convert strings in file to ints---------------------------------
//Getting information from the file about locations

int *pointer;
pointer = findNewLines();
static int linenopos[11];
try{

    for (int i = 0; i < 11; i++){
        linenopos[i] = *(pointer + i);
    }

    std::cout << e.what() << std::endl;
