Answer to Question #279458 in C++ for Kyut

Question

The area of a triangle whose sides a, b, and c can be computed by the formula:

𝑨𝒓𝒆𝒂 𝒐𝒇 𝑻𝒓𝒊𝒂𝒏𝒈𝒍𝒆 = √𝑠((𝑠 − 𝑎)(𝑠 − 𝑏)(𝑠 − 𝑐))

where S = (a+b+c)/2. On the other hand, the hypotenuse of a right triangle can be computed using the

formula:

Answer 1

#include<iostream>
#include<cmath>

using namespace std;

void Menu()
{
	cout<<"\nWhat do you want to compute?\n"
		<<"A - Area of a triangle\n"
		<<"H - Hypotenuse of a right triangle\n"
		<<"E - Exit program"
		<<"Your choice: ";
}

void countArea()
{
	double a,b,c;
	cout<<"Please, enter a value for side a: ";
	cin>>a;
	cout<<"Please, enter a value for side b: ";
	cin>>b;
	cout<<"Please, enter a value for side c: ";
	cin>>c;
	double S=(a+b+c)/2;
	double area=sqrt(S*(S-a)*(S-b)*(S-c));
	cout<<"The area of yor triangle is "<<area;
}

void countHypotenuse()
{
	double a,b,c;
	cout<<"Please, enter a value for side a: ";
	cin>>a;
	cout<<"Please, enter a value for side b: ";
	cin>>b;
	double hyp= sqrt(a*a+b*b);
	cout<<"The hypotenuse of yor right triangle is "<<hyp;
}

int main()
{
	char ch;
	do
	{
		Menu();
		cin>>ch;
		switch(ch)
		{
			case 'A':case 'a':
			{
				countArea();
				break;
			}
			case 'H':case 'h':
			{
				countHypotenuse();
				break;
			}
		}
	}while(ch!='E'&&ch!='e');	
}
