Can anyone help me find a way to achieve the same result with loops without having to call function over function

Question

#include <iostream>
#include <cmath>
using namespace std;

const double c=2015;
double b,z,y,b1,b2,b3,b4;
double s_b(double x);

int main() {
cout<<"enter the value of your birth"<<endl;
cin>>y;
/*this should trigger four birth month calculations
the previous becomes the new input of the other function
that is how they are linked */

b1=s_b(y);
b2=s_b(b1);
b3=s_b(b2);
b4=s_b(b3);

}

double s_b(double x)
{
z=sqrt(c*(x-1));
cout<<z<<endl;
return z;}

Answer 1

Personally, looks like you got most of it done so the little bit I did is nothing.
