新手求帮忙~~帮我看下这代码哪儿错了~~不是特别会~~混混脸熟
#include <iostream>

using namespace std;

main()
{
int a1,b1,c1,v1;
cout<<"press three numbers:"<<endl;
cin>>a1>>b1>>c1>>endl;
if (a1>b1)
v1=a1;
else v1=b1;
if (c1>v1)
cout<<"the number is:"<<c1<<endl;
else ;
cout<<"the numbers is:"<<v1<<endl;
return 0;
}

[解决办法]
cin >> a1 >> b1 >> c1;
不要后面的endl
