其实还是和杭电上的那一题一样
不过我想明白啦
不用纠结这么多
想传就传
任性╭(╯^╰)╮
#include<stdio.h>
#include<math.h>
int main() {
int T;
scanf("%d",&T);
while(T--) {
double x1,y1,x2,y2;
scanf("%lf %lf %lf %lf",&x1,&y1,&x2,&y2);
printf("%.2lf
",sqrt(pow(x1-x2,2)+pow(y1-y2,2)));
}
return 0;
}
标程也暂时没想到什么亮点
不过就当是再欣赏欣赏C++了
#include<iostream>
#include<math.h>
#include<iomanip>
using namespace std;
int main() {
/*freopen("1.txt","r",stdin);
freopen("2.txt","w",stdout);*/
double x1,x2,y1,y2,m;
double a;
cin>>m;
while(m--) {
cin>>x1>>y1>>x2>>y2;
a=sqrt((double)((x1-x2)*(x1-x2)+(y1-y2)*(y1-y2)));
cout.setf(ios::fixed);
cout<<setprecision(2)<<a<<endl;
}
return 0;
}
