C++编译错误

C++ compile error

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
    ifstream inputFile;
    string example;
    int numbers,
    totalNumbers = 0;
    // Prompt user to input name of the file to open
    cout << "Please enter the name of the program" << endl;
    cin >> example;
    // Open the input file that is assigned to the variable 'example'
    inputFile.open(example.c_str());
    // If the file successfully opened, process it
    if(inputFile)
    {
        // Loop until the EOF is reached
        while(inputFile >> numbers) // If a value was read
        {
            totalNumbers += numbers;
        }
        // Close the file
        inputFile.close(example.c_str());
        cout << totalNumbers;
    }
    else 
    {
        // Display an error message
        cout << "could not access file";
    }
    return 0;
}

错误如下:

fileAdder.cpp: 在函数 'int main((' 中:fileAdder.cpp:36:40:错误:调用"std::basic_ifstream::关闭(const char*("没有匹配函数 inputFile.close(example.c_str(((; ^文件添加.cpp:36:40:注意:候选人是:在 fileAdder.cpp:8:0 中包含的文件中:/usr/include/c++/4.8.2/fstream:576:7: 注意: void std::basic_ifstream<_CharT, _Traits>::close(( [_CharT = char; _Traits = std::char_traits] 关闭(( ^/usr/include/c++/4.8.2/fstream:576:7:注意:候选人需要 0 个参数,提供 1

>ifstream::close不接受任何参数。

将第 36 行更改为inputFile.close();

删除 example.c.str((

正确的陈述是:

inputFile.close();

我们不需要传递参数
