    String help

    How do you create a string from a character array?

    Better yet, how do you read from a line from a file and then assign that line to a string? The getline method from the ifstream class requires a *char as it is...

    char *line;
    //manipulate line
    std::string s = line;
    std::string s= ...;
    s = line;
    s += line;

    Use the getline method that works with strings:
    #include <iostream>
    #include <string>
    int main()
        std::string input;
        std::getline(std::cin, input);
        std::cout << input << std::endl;
    Best part - you don't have to worry about the length of the input.
