My C++ code is not running any numbers ???

[ImaniNicole1]

I have no idea why this is not giving me any numbers.
It is supposed to be reading x=__ y=___ but instead it is only giving me my first cout .

//Imani Jones' Output of Her First Program
#include <iostream>
#include <cmath> 
using namespace std;
int main () 
{
    cout<<"My name is Imani Jones and this is the output of my first program."<<endl<<endl;
    double x, y;
    
        for (x=-3.5;x=3;x=x+0.5) 
    { y=((-4*x)*x*x+(4*x)*x+(25*x)-25)/ ((sqrt(4*x)*x+2)+3*  abs(x+1.5));
    
    if (x<0)
    cout<<" Y is negative "<<endl;
    if (x==0) 
    cout<< "Y is positive "<<endl;
    if (x>0)
    cout<< "Y is positive "<<endl<<endl;
    } 
    
   std::cout <<"My First Program is Complete"<< std::endl; 
   system ("pause");
 return 0; 
}

Just pointing this out: for(x=-3.5;x=3;x=x+0.5)

With x being assigned 3, then the condition for the loop will always equal TRUE and will never end.

Also, you shouldn't use floats for comparisons. They're not accurate.

apart from fixing the loop where does your code instruct the print out of x and y?
