    Question newbie cin help

    Ok im new at this and trying to learn but im having problems trying to write an or function for cin. Heres what im trying to do but the or function doesnt work. It will run but it always comes up false.

    cin.getline ( resp1, 50 );
    if ( strcmp ( resp1, "answer1 || answer2") == 0)
       cout<<"Outputted text"<<"\n";
       cout<<"outputted text"<<"\n";
    I Hope someone can help me out. if you have any ideas or think you can help let me know.

    Let me guess: you want to check if resp1 is equal to "answer1" or "answer2". The solution is to write:
    if (strcmp(resp1, "answer1") == 0 || strcmp(resp1, "answer2") == 0)
    But really, you should be using std::string, in which case your entire snippet could be simplified to:
    getline(cin, resp1);
    if (resp1 == "answer1" || resp1 == "answer2")
       cout << "Outputted text\n";
       cout << "outputted text\n";

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
