The logic of sinc function.

closed account (oLNTURfi)
I'm having trouble with a problem. The problem asks that I use the sinx/x function and produce a table of values for the function on a user entered interval. I'm just starting out with C++ and having a hard time with this so any help would be greatly appreciated. Here's what I have so far:
#include <iostream>
#include <cmath>

using namespace std;


double sinc(const double x)




int main()
{
{
if (x==0)
return 1;
return sin(x)/x;

}

double a,b


cout<<"Enter the values for the interval with"<<"\na = starting value"<<"\nb = ending value"<<endl;
cout<<"a = "
cin>>a>>endl;
cout<<"b = "
cin>>b>>endl;

do sinc(x);
for (x = a; x<= b; x ++)
cout<<"_____________________________________";
cout<<"\n "<< a << " "<< sinc(a)

}

What I want to do is have the data displayed in a table with values of x displayed on corresponding line with function value at the x value

Yes, but additionally how would I continue the table for the interval?
