Answer to Question #185649 in C++ for Puja

Question

a. Define an enumeration type, triangleType, that has the values scalene, isosceles, equilateral, and noTriangle.

b.   Write a function, triangleShape, that takes as parameters three num- bers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle. (Note: In a triangle, the sum of the lengths of any two sides is greater than the length of the third side.)

c.   Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle.

Answer 1

#include<iostream>

using namespace std;

enum TriangleType {scalene, isosceles, equilateral, noTriangle};
//a function, triangleShape, that takes as parameters three numbers, each of which represents the length of a side of the triangle. 
//The function should return the shape of the triangle. 
//(Note: In a triangle, the sum of the lengths of any two sides is greater than the length of the third side.)
TriangleType triangleShape(int side1,int side2,int side3){
	if(side1<=0 || side2<=0 || side3<=0){
		return noTriangle;
	}
	//If all sides are equal
	if(side1==side2 && side2==side3){
		return equilateral;   
    }
	//If any two sides are equal 
    else if(side1==side2 || side1==side3 || side2==side3){
       return isosceles;
    }
    else{
		//If none sides are equal 
       return scalene;
    }
}

int main(){
	int side1;
	int side2;
	int side3;
	// Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle.
	cout<<"Enter side 1: ";
	cin>>side1;
	cout<<"Enter side 2: ";
	cin>>side2;
	cout<<"Enter side 3: ";
	cin>>side3;
	//Display result
	if(triangleShape(side1,side2,side3)==scalene){
		printf("Triangle is scalene\n\n");
	}
	if(triangleShape(side1,side2,side3)==isosceles){
		printf("Triangle is isosceles\n\n");
	}
	if(triangleShape(side1,side2,side3)==equilateral){
		printf("Triangle is equilateral\n\n");
	}
	if(triangleShape(side1,side2,side3)==noTriangle){
		printf("It is not a triangle\n\n");
	}
	system("pause");
	return 0;
}
