我是新手，想问一下C++构造类时的错误

Question

#include <iostream>#include "coordinate.h"using namespace std;class Line{public:   Line(int x1,int y1,int x2,int y2);   ~Line();   void setA(int x,int y);   void setB(int x,int y);   void printinfo();private:   Coordinate m_coorA;   Coordinate m_coorB;};Line::Line(int x1,int y1,int x2,int y2):m_coorA(x1,y1),coorB(x2,y2){   cout<<"Line"<<endl;}Line::~Line(){    cout<<"~Line"<<endl;}void Line::setA(int x,int y){    m_coorA.setX(x);    m_coorA.setY(y);}void Line::setB(int x,int y){    m_coorB.setX(x);    m_coorB.setY(y);}void printinfo(){    cout<<"m_coorA.getX()"<<" "<<"m_coorA.getY()"<<endl;    cout<<"m_coorB.getX()"<<" "<<"m_coorB.getY()"<<endl;}错误提示：class "line" does not have any field named "coorB"

Answer 1

Line初始化错误

Line::Line(int x1,int y1,int x2,int y2):m_coorA(x1,y1),coorB(x2,y2)中的coorB应该改成m_coorB

Answer 2

你好。根据错误提示，你的类大小写错误了。定义时为Line,示例化时为line。
