where is 数据？

#include<bits/stdc++.h>
#define int long long
using namespace std;
signed main() 
{
	double a,b,c;
	cin>>a>>b>>c;
	cout<<a*b/1.0/c;
}

SB!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

可用sort排序，默认从小到大，即升序，那就得开数组a，开大小3即可。排完序后求三角形高就是啊a[0]*a[1]/a[2]。注意：得用double！

Code

#include <bits/stdc++.h>
using namespace std;
int main(){
	double a[3];
	cin>>a[0]>>a[1]>>a[2];
	sort(a,a+3);
	cout<<a[0]*a[1]/a[2]; 
	return 0;
} 

#include<iostream>
#define int double
using namespace std;
int a,b,c;
signed main(){
	cin>>a>>b>>c;
	cout<<a*b*1.0/c;
}

消失的数据。

#include<bits/stdc++.h>
#define int long long
#define INF 0x3f3f3f
using namespace std;
double a,b,c;
signed main(){
	cin>>a>>b>>c;
	printf("%.1lf",a*b/c);
	return 0;
}

不是哥们 数据呢

#include<bits/stdc++.h>
using namespace std;
int main()
{
	int a[3];
	cin>>a[0]>>a[1]>>a[2];
	sort(a,a+2);
	printf("%.1f",a[0]*1.0*a[1]/a[2]);
	return 0;
}
