Array
The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

write a c++ code please test it

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax²+bx+c. Where a, b, c, ER and a * 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f(x). The roots of a quadratic equation are the values of the variable that satisfy the equation. They are also known as the "solutions" or "zeros" of the quadratic equation. For example, the roots of the quadratic equation x²7x + 10 are *₁ = 2 and ₂ - 5 because they satisfy the equation (i.e. when each of them is substituted in the given equation we get 0). The first step to solve the equation is to find the determinant which equals 6² 4ac. Based on the determinant value, we have three possibilities for the equation roots: ● If determinant > 0, the equation has two real and different roots which are: x1 = and -b-√determinant 2a -b+√determinant x2 = 2a If determinant = 0, the equation has one -b real root which is: x = 2a • If determinant < 0, then the equation has two complex (i.e. not real) roots which ✓determinant -i and 2a are: x1 = -b 2a X2 = -b 2a determinant 2a • ∙i. In this question, you are asked to write a program that finds the roots of any quadratic equation. The program requests the user to insert the three coefficients a, b, and c, respectively and outputs the values of the roots as follows: • If there are two real different roots, the program prints the root ₁ then the root 2 with a single space between them. • If there is a single real root, the program prints the root only once. • If there are two complex different roots, the program prints the root ₁ then the root x2 on a new line. )
