Question

help im alittle lost my teacher posted all this its suppose to be in C++ language.

can yoh leave comments ans type the code thank you

Write a C++ program that accepts the lengths of three sides (a,b,c) of a triangle as input from the user Validate the user input, so that sides a, b, c can only be POSITIVE. The program output should indicate whether or not the triangle is an Equilateral Triangle, a Right Triangle, Isosceles which is Not Equilateral, or some Other type of triangle. Set up the program so the user can choose to repeat the program, Iif desired. Test your program for the 4 types of triangles, and submit the output with your C++ program. Use the Sample Run data.

Answer 1

Here is the required C++ program for the same. Write a comment if you have any queries. Thanks!

#include <iostream>

using namespace std;

//method to check the type of triangle

string check_type( int arr[] ){

  

                string type = "";

                int a=arr[0], b=arr[1], c=arr[2];

               

                if( a==b && b==c ){

                                type = "EQUILATERAL triangle! (all sides are equal)";

                }

                else if( a==b || b==c || a==c ){

                                type = "ISOSCELES triangle, where only two sides are equal";

                }

                else if( ((a^2+b^2)==(c^2)) || ((a^2+c^2) ==(b^2)) || ((b^2+c^2) ==(a^2)) ){

                                type = "RIGHT triangle";

                }

                else{

                                type = "OTHER kind of triangle, NOT ISOSCELES, NOT RIGHT and NOT EQUILATERAL";

                }

               

                return type;

}

int main(){

                string side_name[3] = {"A","B","C"}; //storing side names A B C

                int side_value[3]; //side values

                int choice=1; //by default you want to check for the first time

               

                do{

                for(int i=0; i<3; i++){

                                cout<<"Please enter side "<<side_name[i]<<": ";

                                cin>>side_value[i];

                               

                                if( side_value[i] <= 0 ){

                                                cout<<"Value entered must be positive!\n";

                                                i--;

                                }

                }

                               

                cout<<"This is an "<<check_type(side_value);

               

                cout<<"\nWould you like to repeat(1-Yes,2-No): ";

                cin>>choice;

                }while(choice == 1);

               

                return 1;

}
