    A string is a type which holds any sequence of characters, typically a word or sentence. std::string is a robust implementation of the concept in the C++ standard library.

    In general, a string is a line of text. Example: "This is a string"

    In C, there are no strings. Instead, you use an array of individual characters. The last value in the array is always 0 (null) which marks the end of the string. Example:

    char[] name = "Chris";

    which is actually an array of type char: 'C', 'h', 'r', 'i', 's', '\0'

    In C++, a new typedef is added called std::string, which is actually a template class (basic_string<T>) being called as basic_string<char>.

    It's basically a template that wraps your normal character array and gives you an easier interface to work with.

    To use a string in a function that reacquires a char[] all you have to do is:

    void printname(const char* name);

    string name = "Chris";
    printname( name.c_str() );
