7.14.1.Overloading ambiguity: float and double

#include <iostream> 

using namespace std; 

 

float f(float i); 

double f(double i); 

 

int main() 

{ 

  // unambiguous, calls f(double) 

  cout << f(10.1) << " "; 

 

  // ambiguous 

  //cout << f(10); // Error! 

 

  return 0; 

} 

 

float f(float i) 

{ 

  return i; 

} 

 

double f(double i) 

{ 

  return -i; 

}
