编译器/链接器错误

标签: c++ linker linker-errors

我正在尝试使我的程序工作(与之前的程序不同)并且我仍然得到一些编译器/链接器错误我不知道如何修复,任何人都可以指导我修复链接器/编译器或其他什么解决方案是吗?

这是构建日志即时获取:

这是我的主要文件:

#include "Complex.h"
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
using namespace std;

int main()
{
ofstream outputfile;
ifstream inputfile;
string str;
double realpart;
double imaginarypart;
int symbol;
char ch;
string strone;
string strtwo;
complexType sum;
int counter = 0;

inputfile.open("complex.txt");
if(inputfile.fail())
{
    cout << "File opening failed." << endl;
    exit(1);
}

outputfile.open("complexObj.txt");

inputfile >> str;
while(inputfile)
{
    symbol=str.find("+");
    ch = '+';
    if(symbol < 0)
    {
        symbol = str.find("-");
        ch = '-';
    }
    stringstream streamin(str);
    getline(streamin, strone, ch);
    getline(streamin, strtwo, 'i');

    realpart= atof(strone.c_str());
    imaginarypart= atof(strtwo.c_str());

    complexType outpobj(realpart, imaginarypart);
    counter++;

    outputfile << "Object " << counter << "-" << outpobj << endl;

    inputfile.close();
    outputfile.close();

    return 0;
}

}

我的标题类文件:

#ifndef COMPLEX_H
#define COMPLEX_H
#include <iostream>


class complexType
{
friend std::ostream& operator<<(std::ostream& os, const complexType& obj);
public:
  complexType();
  complexType(double r, double i);
  complexType operator+(const complexType& objtwo);
private:
    double real;
    double imagine;
};

#endif // COMPLEX_H

这是我的班级cpp文件:

#include "Complex.h"
#include <iostream>
using namespace std;


complexType::complexType()
{
real=0;
imagine=0;
}

complexType::complexType(double r, double i)
{
real=r;
imagine=i;
}

ostream& operator<<(ostream& os, const complexType& obj)
{
os << obj.real << "," << obj.imagine;
return os;
}

complexType complexType::operator+(const complexType& objtwo)
{
complexType sum;
sum.real = real + objtwo.real;
sum.imagine = imagine + objtwo.imagine;
return sum;
}

我很抱歉提出类似的问题,但我无法弄清楚我的链接器或编译器有什么问题。

答案 0 :(得分:0)

我觉得complex.h是一个保留名称。尝试重命名标题,它应该可以正常工作。
