Thread: 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?

{
    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;
}

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

Both are same.

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