Answer to Question #176321 in C++ for Geeta Deshlahre

Question

Create a class Triangle. Include overloaded functions for calculating area. Overload

assignment operator and equality operator.

Answer 1

#include <iostream>
#include <cmath>
using namespace std;




class Triangle
{
private:
	float a,b,c,h;
public:


	Triangle(){}


	Triangle(float a,float b,float c){
		this->a=a;
		this->b=b;
		this->c=c;
	}
	Triangle(float b,float h){
		this->b=b;
		this->h=h;
	}


	float area(){
		cout<<a;
		return area(this->a,this->b,this->c); 
	}
	float area(float a,float b,float c){
		float p=(a+b+c)/2;
		return sqrt(p*(p-a)*(p-b)*(p-c)); 
	}
	// overloaded functions for calculating are
	float area(float b,float h){
		return (b+h)/2;
	}
	//Overload assignment operator
	Triangle& Triangle::operator= (const Triangle &triangle){
		// do the copy
		this->a = triangle.a;
		this->b = triangle.b;
		this->c = triangle.c;
		return *this;
	}
	//equality operator.
	friend bool operator== (const Triangle &t1, const Triangle &t2){
		return (t1.a == t2.a && t1.b == t2.b && t1.c == t2.c);
	}
};


int main(){
	Triangle triangleABC(18,30,24);
	cout<<"Area of the tringle ABC with sides 18,30,24: "<<triangleABC.area(18,30,24)<<"\n";


	Triangle triangleBH;
	cout<<"Area of the tringle with base 24 and height 18: "<<triangleBH.area(24,18)<<"\n";;


	Triangle triangleCopy=triangleABC;
	cout<<"Area of the copy tringle with base 24 and height 18: "<<triangleCopy.area()<<"\n";;


	if(triangleABC==triangleCopy){
		cout<<"The triangles are equal.\n";
	}else{
		cout<<"The triangles are not equal.\n";
	}


	system("pause");
	return 0;
