Set Threshold

#include <iostream>
using namespace std;

// your code here: declare and define setThreshold(int)
void setThreshold(int x){
    cout << "Threshold set to " << x <<endl;
}
// your code here: declare and define setThreshold(double)
void setThreshold(double x){
    cout << "Threshold set to " << x <<endl;
}

int main() {
   double val;
   cin >> val;
    if (val == (int)val){
        setThreshold(val);
    }
    else
    {
        setThreshold(val);
    }
   return 0;
}
