C++ 使用.open()成员函数C++;
我有一个相当简单的任务,我有两个50个名字的文本文件,我向用户查询文本文件“女孩名字”或“男孩名字”和一个名字,然后程序检查用户输入的名字是否在他们选择的文件中。我想我已经基本了解了,但是当我试图打开第二个文件时,我得到了一个错误的访问代码。我读过关于内存分配的问题,我认为这是我的代码的问题,但是答案超出了我的理解水平,所以我被卡住了C++ 使用.open()成员函数C++;,c++,arrays,exc-bad-access,ifstream,C++,Arrays,Exc Bad Access,Ifstream,我有一个相当简单的任务,我有两个50个名字的文本文件,我向用户查询文本文件“女孩名字”或“男孩名字”和一个名字,然后程序检查用户输入的名字是否在他们选择的文件中。我想我已经基本了解了,但是当我试图打开第二个文件时,我得到了一个错误的访问代码。我读过关于内存分配的问题,我认为这是我的代码的问题,但是答案超出了我的理解水平,所以我被卡住了 #include <iostream> #include <fstream> #include <string> using

在这里,您声明了一个包含一个元素的数组。这个数组包含一个元素。这就是[1]在这里的意思
inFile[0].open("GirlsNamesCanada2015.txt");
inFile[1].open("BoysNamesCanada2015.txt");
然后尝试访问数组中的元素#0和元素#1,这一个元素数组中的第一个和第二个元素。可能会出现什么问题
声明数组时:
type array[n];
这意味着数组包含元素#0到元素#n-1
type array[n];
