visual c ++ error C3867

Question

我在这段代码中遇到了很多问题，我已经解决了大部分问题，但我不知道这里有什么问题。

这是visual studio 2013的构建输出

#include <iostream>

#include <fstream>

using namespace std;

        }
    }

    system("pause");

    inFile.close;
    outFile.close;
}
void tut()
{
    cout << "Enter your equation with each " << endl << "element seperated by a space." << endl;
    cout << "Example: HCl -> H Cl" << endl;
    cout << "If theres more than one ion of each " << endl << "element per equation, enter that " << endl << "ion as many time as it appears." << endl;
    cout << "Example: NaSO4 -> Na S O O O O" << endl;
    system("pause");
}

我已经遍布各个论坛，但似乎没有其他人遇到我的问题。 我在整个代码中评论了我认为问题所在。

我对C很新，所以请不要判断我的简单编码技巧。

Answer 1

在错误消息中显示：

source.cpp(54)
source.cpp(55)

这意味着这些错误分别在第54行和第55行。你会发现那些行是：

inFile.close;
outFile.close;

您可能打算调用这些函数：

inFile.close();
outFile.close();

如果你没有调用函数（并且函数调用需要括号），那么以这种方式提及成员函数的名称是错误的。

但是，更好的设计是使inFile和outFile成为您使用它们的函数内的本地对象。然后，当这些对象超出范围时，文件将自动关闭。
