这很混乱，因为我是C ++的新手。我做了一个函数，该函数返回向量的值，该向量从.txt文件中获取其元素。我制作了单独的向量对它进行排序，但这与这个问题无关。 vector<string> txtToArr(int c) { string tempS; double tempD; int tempI; // Adds data to their respective vectors int count = 0; while (!unList.eof()) { ...

我有任务我必须从文件中读取复数并将其写入另一个文件。在课堂上，我必须为实数和虚数创建两个私有变量。我必须将外部类作为内联函数创建一个更大的函数。 这是我的代码： #include <iostream> #include <fstream> #include <cstdlib> #include <assert.h> using namespace std; class Complex_num { double real, imag; public: Complex_num(){ ...

我正在尝试打开文件并检查其中的单词。从列表中引用了这些被审查的单词。这是我的代码 # These are the emails you will be censoring. # The open() function is opening the text file that the emails are contained in # and the .read() method is allowing us to save their contexts to the following variables...

我写了一个小工具，将给定目录下的所有目录和文件名打印到文件中。该程序可以正常编译，但是在运行该程序后，不会写入该文件。在我看来，这很奇怪。程序代码在下面列出。 在代码的第49行中，当我仅将file用作方法的参数时，没有问题，并且输出文件已写入。请尝试并查看结果。但是，当我使用file.getFileName（）作为参数时，输出文件根本没有被写入！ 非常感谢您的帮助。 /** * This program walks a directory tree * and prints out the direct...
