Invalid Operand?

I'm working on this code which "Tells your future"
and despite my best efforts I cannot seem to fix this:
6_2.cpp: In function âvoid tellFortune(double, double)â:
6_2.cpp:19:35: error: invalid operands of types âdoubleâ and âintâ to binary âoperator%â
double numYears = abs(numYears) % 5;
^
6_2.cpp:20:41: error: invalid operands of types âdoubleâ and âintâ to binary âoperator%â
double numChildren = abs(numChildren) % 6;

Code:

#include <iostream>
#include <cmath>
using namespace std;
void tellFortune(double, double);
int main()
{
double numYears, numChildren;
cout << "This program can tell your future. \n";
cout << "Enter two integers separated by a space: ";        
cin >> numYears >> numChildren;
tellFortune(numYears, numChildren);
return 0;
}
void tellFortune(double, double)
{
double numYears = abs(numYears) % 5;       
double numChildren = abs(numChildren) % 6; 
cout << "\nYou will be married in " << numYears << " years " << "and will have " << numChildren << " children.\n";

Try this:

Code:

#include <iostream>
#include <cmath>

using namespace std;

void tellFortune(double, double);

int main()
{
  int numYears, numChildren;

  cout << "This program can tell your future. \n";  cout << "Enter two integers separated by a space: ";        
  cin >> numYears >> numChildren;

  tellFortune(numYears, numChildren);

  return 0;
}

void tellFortune(int numYears, int numChildren)
{
  auto numYears = abs(numYears) % 5;
 auto numChildren = abs(numChildren) % 6; 

 cout << "\nYou will be married in " << numYears << " years " << "and will have " << numChildren << " children.\n";
}

You're using the same name for the local variables as the parameters.

Didn't notice that. Just C&P'd.
