Does this and this have differences?

Does this code:

Code:

//This programme shows an example of if...else statement
#include <iostream>
#include <string>

int main()
{
    using namespace std;

    string response;

    cout<< "What is your favorite programming language? ";
    cin>> response;
    if (response == "C++")
    cout<< "You have a great taste. "<< response << " is a great language.";
    else
    cout<< "It's not as good as C++, but "<< response<< " is a great programming language too.";

    return 0;
}

have any difference with this code:

Code:

//This programme shows an example of if...else statement
#include <iostream>
#include <string>

int main()
{
    using namespace std;

    string response;

    cout<< "What is your favorite programming language? ";
    cin>> response;
    if (response == "C++")
    cout<< "You have a great taste. C++ is a great language.";
    else
    cout<< "It's not as good as C++, but "<< response<< " is a great programming language too.";

    return 0;
}

If no, which is better?

How about this? Now you can change the specific language easily. I added a newline at the end.

Code:

//This programme shows an example of if...else statement
#include <iostream>
#include <string>

int main()
{
    using namespace std;

    const string bestresponse = "C++";
    string response;

    cout<< "What is your favorite programming language? ";
    cin>> response;
    if (response == bestresponse)
    cout<< "You have a great taste. " << bestresponse << " is a great language.";
    else
    cout<< "It's not as good as " << bestresponse << ", but "<< response<< " is a great programming language too.";
    cout << '\n';

    return 0;
}

    return 0;

wow...nice. I've never thought of using const. By the way, your newline should be this "\n" instead of '/n'.

Both are same.

Both are same.

They are not, which is why robatino fixed the code example. '\n', not '/n', is the new line character.

I think the post was referring to the OP's two code examples in the first post, not my code.

Well, it took me copy'n'paste from the original post and running "diff" to even see the difference.

There is no determinable difference from the executable, but there is of course a small difference in the way the code gets produced by the compiler - there is more code for the first piece of code, since it's referencing the "response" variable to output what is essentially a constant value. For flexibility, robatino's example is better, as everyone agrees.
