complete C++ program, including comments, to do the following:

Your program will compute the values of a formula that expresses y in

terms of x. The formula is:

where B...B means "absolute value of" and (...)1â„2 means "square root

of". (Use the built-in functions for these operations.)

1. The program should start by printing a message saying this is the

output of your first program.

2. Then, it should evaluate the formula starting with x = -3, going up

by 0.5 each time, until x reaches 4. Therefore, it will use values x:

-3, -2.5, ..., -0.5, 0, 0.5, ..., 3.5, 4. For each value of x, the

program should compute the corresponding value of y. It should print

these values together with explanations of what the values represent.

For example, it could print the string 'X = ', then the value of x,

then the string 'Y = ', then the value of y, and then a message. (It

is also possible to use column headings instead if you desire.) The

message should say one of three things:

a) If the value of y is exactly 0, the message should say 'Y IS ZERO'.

b) If the value of y is positive, the message should say 'Y IS

POSITIVE'. c) If the value of y is negative, the message should say 'Y

IS NEGATIVE'.

A typical line of output would then be:

X = -2.5 Y = 1.23456 Y IS POSITIVE (in actuality, this may not be the

value for y).

3. Once you have finished using x = 4, the program should print a

message (underneath the last line of output) stating that the program

is halting. Then, stop.

4. Have your program find which of the y values is closest to 10

(either larger or smaller). have the program print the x value that

gives this closest y value. Also, print how close the y value is to

10.

5. Have your program count how many times the formula yields positive,

negative, and zero results. Print these three values.

So far I have worked with a different program, and had a code done for

it, to help me with this assignment, but I do not understand where I

should be posting them to complete the program. because both of the

problems are similar.
