Question 1- 1.cpp code:
#include #include using namespace std; double SquareRoot(double d) { double x=1; for(int i=0;i<1000;++i) { double t=d/x; x=(x+t)/2; } return x; } int main() { double res=SquareRoot(17); cout.setf(ios::fixed); cout << setprecision(4) << res << endl; return 0; }
Rectangle.cpp code
#include "Rectangle.h" Rectangle::Rectangle(int h,int w) { height=h; width=w; } Rectangle::Rectangle(const Rectangle &other) { height=other.height; width=other.width; } Rectangle & Rectangle::operator=(const Rectangle &other) { height=other.height; width=other.width; return *this; } int Rectangle::getheight() { return height; } int Rectangle::getwidth() { return width; } void Rectangle::setheight(int h) { height=h; } void Rectangle::setwidth(int w) { width=w; } int Rectangle::getArea() { return height*width; } int Rectangle::getCircumference() { return 2*(height+width); }
Question 2- 2.cpp code:
#include#include "Rectangle.h" using namespace std; int main() { Rectangle r(8,5); cout<<"The area is:"<<r.getArea()<<endl; cout<<"The circumference is:"<<r.getCircumference()<<endl; r.setheight(10); r.setwidth(8); cout<<"After the chage"<<endl; cout<<"The area is:"<<r.getArea()<<endl; cout<<"The circumference is:"<<r.getCircumference()<<endl; return 0; }
Rectangle.cpp 2 part code:
#ifndef _RECTANGLE_H #define _RECTANGLE_H class Rectangle { private: int height; int width; public: Rectangle(int h=1,int w=1); Rectangle(); Rectangle (const Rectangle &other); Rectangle & operator=(const Rectangle &other); int getheight(); int getwidth(); void setheight(int h); void setwidth(int w); int getArea(); int getCircumference(); }; #endif
