源程序：
#include <iostream>
using namespace std;
int bigger(int x, int y)
{
if (x > y)
return x;
else
return y;
}
float bigger(float x, float y)
{
if (x > y)
return x;
else
return y;
}
double 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");
return 1;
}
