编译代码时收到一些错误。

我忽略了我的代码,我似乎无法看到它有什么问题。如果有人能指出我需要做什么,我会很感激。我不是在寻找有人为我做这件事,我只是需要一些帮助才能搞清楚。

答案 0 :(得分:0)
circleTypeImp.cpp:在成员函数中 - double circleType :: getRadius()constâ:
circleTypeImp.cpp:10:错误:类型的参数âdouble(circleType ::)()constâ不匹配âdoubleâ
private:
double radius() const;
//...
return radius;
返回成员函数radius()
,它返回一个double,但它不是double。我想,你想要一个成员double radius;
。
circleTypeImp.cpp:在成员函数中 - double circleType :: setAreaCircle()constâ:
circleTypeImp.cpp:15:错误:无效使用成员(你是否忘记了&amp;â?) circleTypeImp.cpp:在成员函数中 - circle circleType :: setCircumference()constâ:
circleTypeImp.cpp:20:错误:无效使用成员(你忘记了&amp;â€?)
在这里,您使用成员功能 radius()
,这不是双倍。
pointTypeImp.cpp:在成员函数中,类型为pointType :: setXCoordinate(double)â:
pointTypeImp.cpp:9:错误:未在此范围内声明âx pointTypeImp.cpp:在成员函数中,类型为pointType :: setYCoordinate(double)â:
pointTypeImp.cpp:14:错误:未在此范围内声明
void pointType::setXCoordinate (double xcoord)
{
xcoord = x;
}
void pointType::setYCoordinate (double ycoord)
{

错误已经说明了,x
和y
都没有声明。这应该是
void pointType::setXCoordinate (double x)
//...
void pointType::setYCoordinate (double y)
//...
