Reorganize the following code, so that you have: Base.hpp, Base.cpp, Derived.hpp, Derived.cpp and main, then compile with a makefile (to do). Look carefully how inheritance works for constructors.
#include<iostream>
class Base{
public:
int x;
int y;
double z;
Base(){};
Base(int a, int b, double c ){
this->x=a;
this->y=b;
this->z=c;
}
~Base(){};
};
class Derived : public Base {
public:
double w;
// Look at this
Derived(int a, int b, double c, double d):Base(a,b,c){
this->w = d;
};;
};
int main(){
Derived d(1,2,3.01,4.02);
std::cout<< d.x <<std::endl;
std::cout<< d.y <<std::endl;
std::cout<< d.z <<std::endl;
std::cout<< d.w <<std::endl;
}Download shape.hpp,polygon.hpp, main.cpp. Then write a proper shape.cpp and polygon.cpp so that you can compile your program. Pay attention to namaspaces.
The following code has a bug. If you try to compile it, you get errors. Fix it.
#include<iostream>
class A {
int i;
public:
int getI(){ return i; }
void setI(int i){ this->i = i; }
};
class B : A {
int j;
public:
int getJ(){ return j; }
void setJ(int j){ this->j=j; }
};
int main(){
B b;
b.setI(10);
std::cout << b.getI() << std::endl;
return 0;
}Complete the following code so that it compiles and the output is:
>Equal(i1, i2): 1
>Equal(d1, d2): 0
>Equal(s1, s2): 1
>Equal(a1, a2): 1
>Equal(a1, a3): 0#include <iostream>
#include <string>
using namespace std;
class A {
public:
int i;
A(){};
A(int a){
this->i=a;
}
~A(){};
/* To do: begin */
something missing...
/* To do: end */
private:
int getI(){ return i;}
void setI(int a){
this->i=a;
}
};
/* To do: begin */
something missing...
/* To do: end */
int main (int argc, char* argv[]) {
int i1 = 10;
int i2 = 10;
cout << "Equal(i1, i2): " << Equal(i1, i2) << endl;
double d1 = 10.5;
double d2 = 3.7;
cout << "Equal(d1, d2): " << Equal(d1, d2) << endl;
string s1 = "Hello";
string s2 = "Hello";
cout << "Equal(s1, s2): " << Equal(s1, s2) << endl;
A a1(1), a2(1), a3(2);
cout << "Equal(a1, a2): " << Equal(a1, a2) << endl;
cout << "Equal(a1, a3): " << Equal(a1, a3) << endl;
return 0;
}You are given the following matrix.hpp and mainM.cpp. Write the proper matrix.cpp.
#include <iostream>
class Matrix{
private:
int rows;
int cols;
int **Mat;
public:
Matrix (const int &rows,const int &cols);
~Matrix ();
void setMatrixValue(int r, int c, int value);
int getMatrixValue(int r, int c) const;
int getMatrixRows() const;
int getMatrixCols() const;
Matrix operator +(const Matrix &other) const ;
Matrix operator *(const Matrix &other) const;
};
std::ostream& operator<<(std::ostream &os, const Matrix &m);
#include "Matrix.hpp"
#include <iostream>
int main(){
Matrix m1(2, 2);
m1.setMatrixValue(0,0,1);
m1.setMatrixValue(0,1,0);
m1.setMatrixValue(1,0,1);
m1.setMatrixValue(1,1,-1);
Matrix m2(2, 2);
m2.setMatrixValue(0,0,1);
m2.setMatrixValue(0,1,0);
m2.setMatrixValue(1,0,0);
m2.setMatrixValue(1,1,1);
std::cout << m1 << std::endl;
std::cout << m2 << std::endl;
std::cout << m1+m2 << std::endl;
std::cout << m2+m1 << std::endl;
std::cout << m1*m2 << std::endl;
std::cout << m2*m1 << std::endl;
return 0 ;
}
