[已解决]关于codeblocks中头文件位置的疑问

栗粒粒

请问用codeblocks时自定义的头文件（.h)和有关头文件里函数的定义一（.cpp)应该放在什么位置才能让main.cpp调用到这个头文件和头文件的定义呢？
现在是把这一个.h文件和两个.cpp文件随便放在了桌面上的一个新建文件夹里。

这是头文件

1. #ifndef COMPLEX_H_INCLUDED
   
2. #define COMPLEX_H_INCLUDED
   
3. class Complex
   
4. {
   
5. public:
   
6.     explicit Complex(double = 0.0, double = 0.0);
   
7.     Complex operator+(const Complex&) const;
   
8.     Complex operator-(const Complex&) const;
   
9.     void print() const;
   
10. private:
    
11.     double real;
    
12.     double imaginary;
    
13. };
    
14. #endif // COMPLEX_H_INCLUDED
    

复制代码

这是头文件里函数的定义

1. #include<iostream>
   
2. #include"Complex.h"
   
3. using namespace std;
   
4. Complex::Complex(double realPart,double imaginaryPart)
   
5. :real(realPart),imaginary(imaginaryPart)
   
6. {
   
7. 
   
8. }
   
9. Complex Complex::operator+(const Complex &operand2) const
   
10. {
    
11.     return Complex(real+operand2.real,imaginary+operand2.imaginary);
    
12. }
    
13. Complex Complex::operator-(const Complex &operand2) const
    
14. {
    
15.     return Complex(real-operand2.real,imaginary-operand2.imaginary);
    
16. }
    
17. void Complex::print() const
    
18. {
    
19.     cout<<'('<<real<<","<<imaginary<<')';
    
20. }

这是main.cpp函数

1. #include<iostream>
   
2. #include"Complex.h"
   
3. using namespace std;
   
4. int main()
   
5. {
   
6.     Complex x;
   
7.     Complex y(4.3,8.2);
   
8.     Complex z(3.3,1.1);
   
9.     cout<<"x: ";
   
10.     x.print();
    
11.     cout<<"\ny: ";
    
12.     y.print();
    
13.     cout<<"\nz: ";
    
14.     z.print();
    
15. 
    
16.     x = y + z;
    
17.     cout<<"\n\nx = y + z:"<<endl;
    
18.     x.print();
    
19.     cout<<" = ";
    
20.     y.print();
    
21.     cout<<" + ";
    
22.     z.print();
    
23. 
    
24.     x = y - z;
    
25.     cout<<"\n\nx = y - z:"<<endl;
    
26.     x.print();
    
27.     cout<<" = ";
    
28.     y.print();
    
29.     cout<<" - ";
    
30.     z.print();
    
31.     cout<<endl;
    
32. }
