using namespace std;

int bigger(int x, int y)

{

if (x > y)

return x;

return y;

}

 

int bigger(float x, float y)

{

if (x > y)

return x;

else

return y;

}

 

int bigger(double x, double y)

{

if (x > y)

return x;

else

return y;

}

 

int main()

{

int xI = 10, yI = 20;

float xF = 30, yF = 40;

double xD = 50, yD = 60;

cout << bigger(xI, yI) << endl;

system("pause");

}
