manageFeatures（字符串输入，字符串输出，字符串命令）似乎我的代码有一些导致调试错误的问题。调试错误消息是：project4.exe中0x00EDDFF6处抛出异常：0xC0000005：访问冲突写入位置0xDDDDDDD。我的代码应该读取输入文件，其中19个信息在一行中被分隔。我打算逐行阅读，将信息保存到“features”结构中。数组的初始大小为10.每当达到完整大小时，它应该是数组大小的两倍。

in.open(input);

features * array = new features[size];
while (getline(in, line))

{
*(temp + i) = *(array + i);
}
array = temp;
size = size * 2;
delete[] temp;
