Question

2. Write a program which, given three values representing the sides of a triangle prints:

* 0 if the values cannot be the sides of any triangle. This is so if any value is negative or zero, or if any length is greater than the sum of the other two.

* 1 If the triangle is equilateral.
* 2 If the triangle is isosceles
* 3 if the triangle is scalene.

Answer 1

HERE IS MY CODE SO FAR:

/*Write a program which, given three values representing the sides of a triangle prints:

* 1 If the triangle is equilateral.
* 2 If the triangle is isosceles

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

int main(){

double a,b,c;

cout<<"enter 3 values of your triangle"<< endl;
cin>>a>>b>>c;

if( (a==b&& a!=c) || (a==c && a!=b) || (b==c && b!=a) ) {
cout<< " This triangle is Isosceles"<<endl;
}
else if( a==b && a==c){
cout<< "This triangle is equilateral"<<endl;
}
else if (a!=b && a!=c){
cout<<" This triangle is scalene"<<endl;
}


return 0;
}
