为什么我通过ifstream&时会出错？

Question

我正在尝试编写一个使用ifstream和scanner来读取文本文件的简单程序.出于某种原因,我收到了这个错误:"In passing argument 1 of 'bool ReadVector(std::ifstream&, Vector<double>&)'".知道我做错了什么吗？

#include <iostream>
#include <fstream>
#include <string>
#include "scanner.h"
#include "genlib.h"
#include "simpio.h"
#include "vector.h"

// prototype
bool ReadVector(ifstream & infile, Vector<double> & vec);

// main
int main(){
    Vector<double> vec;
    ifstream infile;
    infile.open("SquareAndCubeRoots.txt");
    if (infile.fail()) Error("Opening file screwed up");
    bool foo = ReadVector(&infile, &vec); // stub
    cout << foo;
    infile.close();
    return 0;
}

// stub
bool ReadVector(ifstream & infile, Vector<double> & vec){
    return true;
}

ReadVector接受引用,但是你给了一个指针.打电话吧

bool foo = ReadVector(infile, vec);
