    How do I...

    So I'm still just at the very beginning of learning c++.. when making a program that says something like

    Code:
    if (value == 0) {
          break;}
    Thats doable with integers but how do I do it with words so when the user inputs the word "close" it breaks? I don't understand how to use words in it... any help?

    Thanks in advance!

    simple where ever you defin int change it to char ex.

    Code:
    char value
    char wateva
    
    cin>> value; //user input goes here
    if ( value == wateva ) {
    break;
    }
    im a beginner too but is that what you want?

    Use the string class.
    Code:
    #include <iostream>
    #include <string>
    
    int main()
    {
        std::string input;
        std::cout<<"Enter command: ";
        std::cin>>input;
        if(input =="close")
        {
            return 0;
        }
        std::cout<<"You didn't enter close"<<std::endl;
        return 0;
    }
    Woop?

    Code:
    string buffer;
    
    getline (cin, buffer); //or "cin >> buffer;"
    
    if (buffer == "closed")
       break;
    This is just a quick answer, but this is how you would do it: by using a string and testing whether the input is correct. Now you might want to do error checking by changing the buffer to all lower case to insure its not case sensitive.

    Check out the strings tutorials on this site.

    EDIT: Damn prog-bman beat me to it!

    JoshR, just PM that to him, no need to post it. Thanks everyone, all those answers helped a bunch!

    (See, I'm just now learning strings, barely touching on it.)

    Thanks again!

    might i add the using namespace std so you dont have to do std:: b4 cout string and cin and yes josh i know lol jus lazy :P

    I believe he said "word", not character, so he'd either need to change the char into an array, or use a string.

    You can add the using directive if you want to, but that defeats the entire purpose of the namespace. It's usually not important in beginners' programs, but taking the easy/lazy way out is not a good habit to get into.
