Question

cpp program to read a triangle three sides and print"

equilateral" when all the sides are equal and print "isosceles" when

two sides are equal and print "scalene" when all the sides are

different

Answer 1

thanks for the question, here is the complete program in C++

======================================================================

#include<iostream>

#include<cmath>

using namespace std;

int main(){

               

               

                double side_one, side_two, side_three;

                cout<<"Enter the sides of a triangle (separated by space): ";

                cin>>side_one>>side_two>>side_three;

               

               

                if(side_one>0 && side_two>0 && side_three>0) {

                               

               

                                if(abs(side_one-side_two)<=0.00001 && abs(side_one-side_three)<=0.00001){

                                               

                                                cout<<"Its an Equilateral Triangle.";

                                }

                               

                                else if (

                                                                (abs(side_one-side_two)<=0.00001 ||

                                                                abs(side_one-side_three)<=0.00001) ||

                                                                abs(side_three-side_two)<=0.00001){

                                                                               

                                                cout<<"Its an Isosceles Triangle.";

                                }

                                else{

                                               

                                                cout<<"Its an Scalene Triangle.";

                                }

                }

                else{

                               

                                cout<<"Error: Sides cannot be negative.";

                }

}
