定义函数模板，分别求出int型数的两个点间的距离和浮点型数的两点间距离

#include<iostream>#include<cmath>using namespace std;template<typename T>T t_distance(T x1,T x2,T y1,T y2){return sqrt((x1-x2)*(x1-x2)+(y1-y2)*(y1-y2));}int main(){int a,b,c,d;double f,i,j,k;int distance1;double distance2;cout<<"请输入两个整数坐标的数值：";cin>>a>>b>>c>>d;cout<<endl;cout<<"请输入两个浮点数坐标的数值：";cin>>f>>i>>j>>k;distance1=t_distance(a,b,c,d);distance2=t_distance(f,i,j,k);cout<<"两点间的距离："<<distance1<<endl;cout<<"两点间的距离："<<distance2<<endl;return 0;}
