std::max()拯救万物。

code

#include<bits/stdc++.h>
using namespace std;
int a,b;
int main(){
	cin>>a>>b;
	cout<<max(a,b)*max(a,b);
}

#include<bits/stdc++.h> using namespace std; int main() { int a,b; cin>>a>>b; if(a<b) swap(a,b); cout<<a*a<<endl; return 0; }

using namespace std;
int main()
{
	int a,b;
	cin>>a>>b;
	if(a>b)
	{
		cout<<a*a<<endl;
	}
	else
	{
		cout<<b*b<<endl;
	}
   return 0;
}

#include<bits/stdc++.h> using namespace std; int main() { int a,b; cin>>a>>b; cout<<(max(a,b))*(max(a,b))<<endl; return 0;

}

#include<bits/stdc++.h> using namespace std; int main() {int a,b; cin>>a>>b; if(a>b) {cout<<aa; } else {cout<<bb; } return 0; }

#include<bits/stdc++.h> using namespace std; int main() { double a,b,c,max; cin>>a>>b; max=(a>b)?a:b; c=max*max; cout<<c; return 0; }

#include<bits/stdc++.h>
using namespace std;
int main()
{int a,b;
cin>>a>>b;
cout<<(max(a,b))*(max(a,b))<<endl;
return 0;
}

#include<bits/stdc++.h> using namespace std; int main() { int a,b,ans; cin>>a>>b; ans=(a>b?aa:bb); cout<<ans; return 0; }

现在知道swap的用法了吧 #include<bits/stdc++.h> using namespace std; int main () { int a,b; cin>>a>>b; if(a>b) { cout<<aa; } else { swap(a,b); cout<<aa; } return 0; }
