为什么这个c++程序在多个文件上通过命令提示符运行时会崩溃，而在单个文件上运行时却不会

Why this C++ program crashes specifically when run through command prompt on multiple files but not when run on individual files?

int main() {
  string xs;
  string* atom=new string[60000];
  string* aa=new string[60000];
  string* pos=new string[60000];
  string* aaid=new string[60000];
  string* chain=new string[60000];
  string* X=new string[60000];
  string* Y=new string[60000];
  string* Z=new string[60000];
  string* occupancy=new string[60000];
  string* bfactor=new string[60000]; 
  ifstream inFile;
  inFile.open ("1ASO.pdb"); //similar to 1ASO.txt
  //middle codes
  delete [] atom;
  delete [] aa;
  delete [] pos;
  delete [] aaid;
  delete [] chain;
  delete [] X;
  delete [] Y;
  delete [] Z;
  delete [] occupancy;
  delete [] bfactor;
  inFile.close();
}

这段代码工作得很好，但是当我将其更改为通过命令提示符输入文件时(如下所示)，对于特定文件(如1ASO.pdb)，它会崩溃。我在命令提示符中使用以下命令运行所有pdb文件的程序。
For %f in (*.pdb)执行程序"%f"
我的猜测是我正在做动态内存分配错误，但不确定如何修复它。

 int main(int argc, char* argv[]) {
   string xs;
   string* atom=new string[60000];
   string* aa=new string[60000];
   string* pos=new string[60000];
   string* aaid=new string[60000];
   string* chain=new string[60000];
   string* X=new string[60000];
   string* Y=new string[60000];
   string* Z=new string[60000];
   string* occupancy=new string[60000];
   string* bfactor=new string[60000]; 
   ifstream inFile;
   inFile.open (argv[1]); //similar to 1ASO.txt
   //middle codes
   delete [] atom;
   delete [] aa;
   delete [] pos;
   delete [] aaid;
   delete [] chain;
   delete [] X;
   delete [] Y;
   delete [] Z;
   delete [] occupancy;
   delete [] bfactor;
   inFile.close();
 }

你分配这些字符串有什么特殊的原因吗?为什么不直接将它们声明为局部变量呢?

你看过argv[1]是什么吗?您确定这是您想要的文件名吗?
