                                        int num result;

                                        cout<<"\n Enter any Number\n";

                                        cin>>num;

                                        result = num*num;

                                        cout<<"\n The result is"<<result;

Answer 2

#include<iostream.h> #include<conio.h> #include<math.h> void main() { int num,ans; clrscr(); cout<<"Enter any Num: "; cin>>num; ans=pow(num,0.5); cout<<"\n Squre of "<<num<<" is: "<<ans; getch(); }

Output

Enter any Num: 9 Squre of 9 is: 3
