rt 代码如下

#include<iostream>
#include<cmath>
#include<algorithm>
using namespace std;
int main(){
	int a[114],sum;
	for(int i=0;i<3;i++){
		cin>>a[i+1];
	}
	sort(a,a+3);
	if(a[1]*a[1]+a[2]*a[2]>a[3]*a[3]){
		cout<<"Acute triangle"<<endl;
	}
	if(a[1]*a[1]+a[2]*a[2]==a[3]*a[3]){
		cout<<"Right triangle"<<endl;
	}
	if(a[1]*a[1]+a[2]*a[2]<a[3]*a[3]){
		cout<<"Obtuse triangle"<<endl;
	}
	if(a[1]==a[2]||a[2]==a[3]||a[1]==a[3]){
		cout<<"Isosceles triangle"<<endl;
	}if(a[1]==a[2]&&a[2]==a[3]){
		cout<<"Equilateral triangle"<<endl;
	}if(a[1]+a[2]<=a[3]){
		cout<<"Not triangle";
		return 0;
	}
	return 0;
}

怎么我什么题都不会
