我这样fun重载竟然报错了。。改成double就行,但是float就不行!什么鬼??
#include"iostream"
using namespace std;
void fun(int x = 1,int y = 2,int z = 3);
void fun(float x,float y);
int main()
{
fun(0.9,0.1);
system("pause");
return 0;
}
void fun(int x,int y,int z)
{
cout <<x<<','<<y<<','<<z<<endl;
}
void fun(float x,float y)
{
cout<<x<<','<<y<<endl;
}error C2668: 'fun' : ambiguous call to overloaded function
could be 'void fun(float,float)'
or 'void fun(int,int,int)'
