    Help with varable type

    I'm using Devc++ to make my programs. When I try using the varable type string it won't reconize it. Is string not a varable type anymore or is there a bug? And if it isn't a varable type then ow do I get input setentases(sorry for my bad spelly :-\) from the user?

    #include <string>

    Use the std namespace.

    EDIT:
    Note that string is a type defined in the standard library. It is not a language type, but a user-defined type.

    string is a class defined in the standard library. First make sure that the <string> header is included and that you've taken the std namespace into account (string resides in std::). If all of this doesn't work, your version of Dev-C++ is too old, upgrade. Here's a working program that uses std::string's that you can use to test with:
    Code:
    #include <iostream>
    #include <string>
    
    int main()
    {
        std::string name;
    
        std::cout<<"Enter your name: ";
        std::getline(std::cin, name);
        std::cout<<"Hello, "<< name <<'!'<<std::endl;
    }
    My best code is written with the delete key.

    okay what I'm Trying to do is the user inputs an item name. It stores the name. It loops for a product name till he/she inputs 'done'. So how would I store the value he/she inputed?


    Thanks

    Theoretically, you would use an array or vector of string objects:
    Code:
    #include <string>
    #include <vector>
    
    std::vector<std::string> products;
    std::string name;
    
    while (std::getline(std::cin, name) && name != "done")
      products.push_back(name);
    My best code is written with the delete key.
