please answer it in c++ 3c QUESTION 33| Bachelor of Engineering(a) The length of a month varies from 28 to 31 days. In this task you are required tocreate a program that reads the name of a month from the user as a string. Then yourprogram should display the number of days in that month. Display '28 or 29 days' forF'ebruary so that leap years are addressed.(b) A triangle can be classified based on the lengths of its sides as equilateral.isosceles or scalene. All 3 sides of an equilateral triangle have the same length. Anisosceles triangle has two sides that are the same lengths and a third side that is adifferent length. If all of the sides have different lengths then the triangle is scalene.Write a program that reads the lengths of 3 sides of triangles from the user. Display amessage indicating the type of the triangle.f(r) = ar? - lr - e(c) A univariate quadratic function has the form:where a, b and e are constants, and a is non-zero. The roots of a quadratic functioncan be found by finding the values of x that satisfy the quadratic equation. A quadratic function may have 0, 1, or 2 real roots. These roots can be computedusing the quadratic formula, shown below:ー6にVF- turrootThe portion of the expression under the square root sign is called the discriminant. Irthe discriminant is negative then the quadratic equation does not have any realroots. If the discriminant is 0, then the equation has one real root. Otherwise theequation has two real roots, and the expression must be evaiuated twice, once usinga plus sign and once using a minus sign, when computing the numerator.Write a program that computes the real roo's of a quadratic function. Your programshould begin by prompting the user for the values of a, b and e. Then it should displaya message indicating the number of real roots, along with the values of the realroots (if any).

#include <iostream>#include <cmath>using namespace std; int main() { float a, b, c,…
