Redo the program given where you have to define and use the following functions: (a) isTriangle - takes 3 sides of a triangle and returns true if they form a triangle, false otherwise. (b) isIsosceles - takes 3 sides of a triangle and returns true if they form an isosceles triangle, false otherwise. (c) isEquilateral - takes 3 sides of a triangle and returns true if they form anequilateral triangle, false otherwise. (d) isRight - takes 3 sides of a triangle and returns true if they form a right triangle, false otherwise. (e) your program should run continuous until the user wants to quit The given program: #include <iostream> #include <cmath> using namespace std; // Constant Declarations const double E = .0001; int main() { double side1, side2, side3; bool isTriangle, isRight, isEquilateral, isIsosceles; cout << "Enter the lengths of the 3 sides of a triangle -- "; cin >> side1 >> side2 >> side3; isTriangle = side1 + side2 > side3 &&side1…

What do parentheses do in mathematical equations?   a. Ensure addition functions are performed before subtraction functions   b. Ensure multiplication functions are performed before division functions   c. Ensure multiplication functions are performed before addition functions   d. Ensure that whatever operation is inside the parentheses is performed first
