We always use getline statement to store a string otherwise it will not store the letters after a space. instead of cin>>subject;
Use:
 getline(cin,subject);

You have two main errors in your program.

1). Use insert symbols before inserting anything in cout statement.

 cout << "Nice !! "<<subject<< " is a good subject";

2); If your subject name includes  a space in between then don't use cin statement to get the value from the user. because you are storing a string. Use this getline statement to get the value.

getline(cin,subject);

Use this corrected code:

#include <iostream>
#include <string>

using namespace std;

int main()
{
    string subject;
    cout << "What is your favourite subject ==> ";
    getline(cin, subject);
    cout << "Nice !! "<<subject<< " is a good subject";
    return 0;
}

OUTPUT:

 

What is your favourite subject ==> Physical Education                                                                         

Nice !! Physical Education is a good subject

I hope this will help you.
