原题是使用重载函数的方法定义两个函数，用来分别求出两个int型数的点间距离和浮点型数的点间距离。
#include<iostream.h>
#include<math.h>
int distan(int,int);
float distan(float,float);
void main()
{
int distance1;
float distance2;
distance1=distan(1,2);
distance2=distan(1.35,2.78);//出错处
cout<<distance1<<distance2;
}
int distan(int x,int y)
{
int c=abs(x-y);
return c;
}
float distan(float x,float y)
{
float c=abs(x-y);//错误处
return c;
}

.请高手帮帮忙指点一下 小弟感激不尽

float换成double就好了
