Visual Studio 2010不構建頭文件更新

Question

我使用Visual Studio 2010與C++，儘管將預編譯頭文件選項設置爲'不使用預編譯頭文件'，但它仍然堅持忽略頭文件。在另一臺機器上，使用相同的設置可以正常工作。我怎樣才能解決這個問題？

Complex.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); 
}; 

Complex.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

您需要定義，例如，getReal（）爲複雜:: getReal（）在你的.cpp文件中。另外，getReal（）之後的所有成員函數都是這種情況。
