两个代码都有问题，希望大佬帮忙修正一下
#include<iostream>using namespace std;
class Point{
protected:
double x;
double y;
public:
Point(double a=0,double b=0){
x=a;
y=b;
}
double getx(){
return x;
}
double gety(){
return y;
}
void print(){
cout<<"("<<x<<","<<y<<")"<<endl;
}
};
class Distance:public Point{
protected:
Point p1(4,5);
public:
Distance(double c,double d):Point(c,d)
void print(){
cout<<sqrt(pow(p1.getx()-c,2)+pow(p1.gety()-d))<<endl;
cout<<"("<<p1.getx()<<","<<p1.gety()<<")("<<c<<","<<d<<")"<<endl;
}
};
int main(){
Distance d1(0,0);
d1.print();
return 0;
}
#include<iostream>
using namespace std;
class Square{
protected:
double bc;
double zc;
public:
Square(double bc=0);
void virtual f()=0;
void print(){
cout<<zc<<endl;
}
};
class Rectangular:public Square{
double bc1;
public:
Rectangular(double a,double b):Square(a){
bc1=b;
}
void f(){
zc=2*(bc+bc1);
}
void print(){
cout<<bc<<bc1<<endl;
print();
}
};
int main(){
Rectangular r1(4,5);
r1.f();
r1.print();
return 0;
}
第一个代码
#include <iostream>
#include <cmath>
using namespace std;
class Point {
protected:
double x;
double y;
public:
Point(double a = 0, double b = 0) {
x = a;
y = b;
}
double getx() {
return x;
}
double gety() {
return y;
}
void print() {
cout << "(" << x << "," << y << ")" << endl;
}
};
class Distance : public Point {
protected:
Point p1;
public:
Distance(double c, double d) : Point(c, d), p1(4, 5) {}
void print() {
cout << sqrt(pow(p1.getx() - x, 2) + pow(p1.gety() - y,2)) << endl;
cout << "(" << p1.getx() << "," << p1.gety() << ")(" << x << "," << y << ")" << endl;
}
};
int main() {
Distance d1(0, 0);
d1.print();
return 0;
}
第二个代码：
#include<iostream>
using namespace std;
class Square {
protected:
double bc;
double zc;
public:
Square(double bc = 0) : bc(bc) {};
void virtual f() = 0;
void print() {
cout << zc << endl;
}
};
class Rectangular : public Square {
double bc1;
public:
Rectangular(double a, double b) : Square(a) {
bc1 = b;
}
void f() {
zc = 2 * (bc + bc1);
}
void print() {
cout << bc << " " << bc1 << endl;
Square::print();
}
};
int main() {
Rectangular r1(4, 5);
r1.f();
r1.print();
return 0;
}
