              来篇题解 科普一下,sqrt函数是计算一个数开根号是多少的函数

              就比方说sqrt(25)是5,因为5*5=25。同理,

              sqrt(36)=6

              ceil是指取比那个数大且离他最近的整数。ceil整数还是这个数本身。比如:

              ceil(3.141)=4

              上代码:

              #include<bits/stdc++.h>
              using namespace std;
              
              int main(){
              	int n;
              	cin>>n;
              	if(ceil(sqrt(n))==sqrt(n))cout<<sqrt(n);
              	else cout<<"No,Chen";
              	return 0;
              }
              

              因为懒所以不加注释了,看得懂吧? 欢迎来luogu找我玩!

                    sqrt函数:计算开方
                    用法:

                    sqrt(double x);
                    

                    作用:返回x的开方。 注意:需要包括库

                    #include <math.h>
                    

                    本题思路:判断n的开方是否为整数。(好像在C++行不通...) 附上本人AC代码:

                    //Write by: FSC711300
                    #include <bits/stdc++.h>
                    using namespace std;
                    int main(){
                        int n;
                        cin>>n;
                        
                        if(int(sqrt(n))*int(sqrt(n))==n){
                            cout<<sqrt(n);
                        }else{
                            cout<<"No,Chen";
                        }
                    }
