Weird table issue.

[Little Duck]

For some reason this table produces several unwanted zeroes in between the values. How do I get rid of the zeroes?

//Inches to centimeters
#include <iostream>
#include <iomanip>
using namespace std;

double Centimeters(double);

int main()
{
    // Set Precision.  I think the issue might be here.
    cout << setprecision(12) << fixed << showpoint;              
    // Chart
    cout << "Inches" << setw(12) << right << "Centimeters";
    cout << "\n------------------------------------------\n";
    // Loop.
    for (double Inches = 0; Inches <= 12; Inches++)
    {
    cout << setw(10) << right << Inches << setw(12) << right << Centimeters(Inches)
    << endl;
    }
    return 0;
    }
    //return as Celsius.
    double Centimeters(double Inches)
    {
    double Centimeters = (Inches * 2.54);

    return Centimeters;
    }

Here is the DOS window that the program outputs.

Yeah, setprecision is the issue. You are setting the precision of your doubles to 12 decimal places. You probably only want 2, or maybe 3 right? So just change setprecsion(12) to setprecision(2).

// Set Precision. I think the issue might be here.
cout << setprecision(12) << fixed << showpoint;

Bingo. What did you expect this would do?
