Write a complete C++ program, including at least one good commen

t, to do the

following: Your program will compute values of a formula that exp

resses y in terms of x.

The formula is:

4x

3

+

8x

2

- 31x - 35

y =

--

----------------------------------

(

10

x

2

+ 1)

1/2

+ 7 * | x + 2.5 |

| | means absolute value);(...)

1/2

means square root use library functions for these

1. The program should start by printing a message giving you

r name and saying this is

the output of your second program.

2. Then it should evaluate the formula starting with x = -5 (ne

gative 5), going up by 0.5

each time until it reaches 4.0. Therefore, it will use these values for x

:-5

,

-4.5, ...,-0.5, 0,

0.5, 1, ..., 3.0, 3.5, 4.0.

For each x value, the program should compute the correspond

ing y value. It should

print these values together with explanations of what the valu

es represent. For

example, it could print the string "X = ", then the value of x, the strin

g "Y = ", the value of

y, and a message. (It is also possible to use column headings and

have your numbers

underneath the headings.)

The message should say one of three things:

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

If the value is positive, the message should say Y IS POSITIVE.

If the value is negative, the message should say Y IS NEGATIVE.

A

typical line of output would look like this (or the values of x

and y can appear

underneath column headings):

X = -2 Y = 0 Y IS ZERO (actually, this one will not be zero)

3. Once you have finished using x = 4.0, the program should

print a message

(underneath the last line of output) saying that your first program i

s complete, then stop.

Write a complete C++ program, including at least one good comment, to do the following: Your program will compute values of a formula that expresses y in terms of x.

Explanation / Answer

#include<stdio.h>
#include<iostream.h>

int main(){
int x=0;
//variable declration
printf("Enter x value:");
float opt=0;
scanf("%d",&x);
if(x1=0);

opt=returnYvalue(x);

}

printf("output is:" opt);

float returnYvalue(int x){

return 4x3+8x2-3x-35/((10x2+1)1/2 +7*|x+2.5|)

}
