メンバー関数のエラーC++

Question

自分のコードをコンパイルするときにいくつかのエラーが発生します。

circleTypeImp.cpp: In member function âdouble circleType::getRadius() constâ: 
circleTypeImp.cpp:10: error: argument of type âdouble (circleType::)()constâ does not match âdoubleâ 
circleTypeImp.cpp: In member function âdouble circleType::setAreaCircle() constâ: 
circleTypeImp.cpp:15: error: invalid use of member (did you forget the â&â ?) 
circleTypeImp.cpp: In member function âdouble circleType::setCircumference() constâ: 
circleTypeImp.cpp:20: error: invalid use of member (did you forget the â&â ?) 
pointTypeImp.cpp: In member function âvoid pointType::setXCoordinate(double)â: 
pointTypeImp.cpp:9: error: âxâ was not declared in this scope 
pointTypeImp.cpp: In member function âvoid pointType::setYCoordinate(double)â: 
pointTypeImp.cpp:14: error: âyâ was not declared in this scope 
pointTypeImp.cpp: At global scope: 
pointTypeImp.cpp:23: error: prototype for âdouble pointType::getXCoordinate(double)â does not match any in class âpointTypeâ 
pointTypee.h:15: error: candidate is: double pointType::getXCoordinate() const 
pointTypeImp.cpp:28: error: prototype for âdouble pointType::getYCoordinate(double)â does not match any in class âpointTypeâ 
pointTypee.h:16: error: candidate is: double pointType::getYCoordinate() const 

私はコードを見落としていて、何が間違っているかを見ているようです。もし誰かが私にそれを指摘することができたら、何が必要なのでしょうか、私はそれを感謝します。私は誰かが私のためにそれをするのを探しているわけではありません、私はちょうどそれを考え出して助けを必要としています。

Answer 1

circleTypeImp.cpp: In member function âdouble circleType::getRadius() constâ:
circleTypeImp.cpp:10: error: argument of type âdouble (circleType::)()constâ does not match âdoubleâ

private: 
    double radius() const; 
//... 
return radius; 

あなたは、二重を返すメンバ関数radius()を返しますが、それは、二重ではありません。私は推測すると、代わりにメンバーdouble radius;が欲しかった。ここ

circleTypeImp.cpp: In member function âdouble circleType::setAreaCircle() constâ:
circleTypeImp.cpp:15: error: invalid use of member (did you forget the â&â ?)
circleTypeImp.cpp: In member function âdouble circleType::setCircumference() constâ:
circleTypeImp.cpp:20: error: invalid use of member (did you forget the â&â ?)

同じ、あなたは二重のないメンバー機能radius()を、使用しています。

pointTypeImp.cpp: In member function âvoid pointType::setXCoordinate(double)â:
pointTypeImp.cpp:9: error: âxâ was not declared in this scope
pointTypeImp.cpp: In member function âvoid pointType::setYCoordinate(double)â:
pointTypeImp.cpp:14: error: âyâ was not declared in this scope

void pointType::setXCoordinate (double xcoord) 
{ 
    xcoord = x; 
} 

void pointType::setYCoordinate (double ycoord) 
{ 
    ycoord= y; 
} 

エラーが、それはすでに、xもyどちらが宣言されていると言います。これは、宣言と定義

double pointType::getXCoordinate() const 
double pointType::getXCoordinate(double) 

pointTypeImp.cpp:28: error: prototype for âdouble pointType::getYCoordinate(double)â does not match any in class âpointTypeâ
pointTypee.h:16: error: candidate is: double pointType::getYCoordinate() const

ここで同じ

間

void pointType::setXCoordinate (double x) 
//... 
void pointType::setYCoordinate (double y) 
//... 

pointTypeImp.cpp: At global scope:
pointTypeImp.cpp:23: error: prototype for âdouble pointType::getXCoordinate(double)â does not match any in class âpointTypeâ
pointTypee.h:15: error: candidate is: double pointType::getXCoordinate() const

不一致でなければなりません。
