Write a C++ program (without a use of global variables) to solve a single quadratic equation of the form:

a*x2 + b*x + c = 0

with the following specific requirements:

1) Reading of coefficients a, b, c shall be done by a function named readCoeffs(). They shall be entered

as double's from the keyboard by an operator, after prompt, as follows:

Enter coefficient a: <operator enters a>

Enter coefficient b: <operator enters b>

Enter coefficient c: <operator enters c>

and returned to the caller as a structure with 3 fields.

2) The actual solution of the equation shall be done by a function named equSolver(), which takes three

coefficients as parameters and returns a structure of three fields: two roots (if they exist) and a boolean

indicator, whether the roots do exist.

3) The function equSolver() shall call another function named discr() to calculate and return the

discriminant necessary to compute the roots.

4) After equation is solved, another function named outResults() shall display on the screen results of the

calculation in the following format:

a) If the solutions (roots) exist in the real domain, the output shall look as follows:

Quadratic equation with the following coefficients:

a: <value>; b: <value>; c: <value>

has the following roots

Root1: <value>; Root2: <value>;

b) In case there are no solutions (roots) in the real domain, the output shall look as follows:

Quadratic equation with the following coefficients:

a: <value>; b: <value>; c: <value>

has no roots in the real domain.

5) All functions shall be placed in a file separate from main(), named funcs.cpp, and a makefile shall

be constructed and used for compilation.

? Form of submission: Two C++ source files named asisgn1.cpp (with main() program) and

funcs.cpp (with functions) should be placed in your account on sanibel in a directory named

assigns (created in your user directory); in addition, the makefile should also be placed there
