c++ - Visual Studio 2010 不构建 header 更新

Question

我正在使用带有 C++ 的 Visual Studio 2010，尽管将预编译 header 选项设置为“不使用预编译 header ”，它仍然坚持忽略我的 header 。在另一台机器上，它使用相同的设置工作正常。我该如何解决这个问题？

复杂.h

#include <cmath>
#include <cstdlib>
using namespace std;

class Complex{

private:
    double real, imaginary, magnitude, angle;
    double rectangularToMagnitude(double, double);
    double rectangularToAngle(double, double);
    double polarToReal(double, double);
    double polarToImaginary(double, double);
public:
    Complex (char, double, double);
    Complex (double, double);
    Complex (double);
    Complex ();

    double getReal();
    double getImaginary();
    double getMagnitude();
    double getAngle();

    void setRectangular(double, double);
    void setPolar(double, double);
};

复杂.cpp

#include "Complex.h"

// Three arguments passed, type and variables.
Complex::Complex(char type, double a, double b)
{
    switch(type)
    {
    case 'R':
    case 'r':
        setRectangular(a, b);
        break;
    case 'P':
    case 'p':
        setPolar(a, b);
        break;
    }
}

// Two arguments passed, assume rectangular.
Complex::Complex (double a, double b)
{
    real = a;
    imaginary = b;
    magnitude = rectangularToMagnitude(a, b);
    angle = rectangularToAngle(a, b);
}

// One argument passed, assume real, used to cast double to complex.
Complex::Complex (double a)
{
    real = a;
    imaginary = 0;
    magnitude = a;
    angle = 0;
}

// No argument passed, assume values of zero.
Complex::Complex ()
{
    real = 0;
    imaginary = 0;
    magnitude = 0;
    angle = 0;
}

// Convert real to imaginary and vice versa.
double Complex::rectangularToMagnitude(double re, double im) {return sqrt((re*re)+(im*im));}
double Complex::rectangularToAngle(double re, double im) {return atan2(im, re);}
double Complex::polarToReal(double ma, double an) {return ma*cos(an);}
double Complex::polarToImaginary(double ma, double an) {return ma*sin(an);}

// Accessors
double getReal() {return real;}
double getImaginary() {return imaginary;}
double getMagnitude() {return magnitude;}
double getAngle() {return angle;}

// Mutators
void setRectangular(double re, double im)
{
    real = re;
    imaginary = im;
    magnitude = rectangularToMagnitude(re, im);
    angle = rectangularToAngle(re, im);
}

void setPolar(double ma, double an)
{
    real = polarToReal(ma, an);
    imaginary = polarToImaginary(ma, an);
    magnitude = ma;
    angle = an;
}

Answer 1

例如，您需要在 .cpp 文件中将 getReal() 定义为 Complex::getReal()。此外，getReal() 之后的所有成员函数都是这种情况。
