Calculating areas of different shapes using function overloading

#include <iostream> using namespace std; class shape { public: void area(int side) { cout << "area of square:" <<side*side << endl; } void area(float radius ) { cout << "area of circle: " << 3.14*radius*radius << endl; } void area(int base,int height) { cout << "area of triangle: " <<0.5*base*height << endl; } void area(float length,float breadth) { cout << "area of rectangle: " << breadth*length << endl; } }; int main() { shape square; /*shape circle; shape triangle; shape rectangle;*/ int side,base,height; float radius,length,breadth; cout<<"square:\n"<<"side:"; cin>>side; square.area(side); cout<<"circle:\n"<<"radius:"; cin>>radius; square.area(radius); cout<<"triangle:\n"<<"base and height :"; cin>>base>>height; square.area(base,height); cout<<"rectangle:\n"<<"length and breadth:"; cin>>length>>breadth; square.area(length,breadth); return 0; }
