    First tell us what it is you don't understand, then someone might be able to help you. If you don't know what you don't understand, go read some more tutorials/books.

    An array is a sequence of items with the same type, such as int or char. A string is a sequence of chars that always end with the '\0' character. A C string is an array of those chars where the last element in the array is the nul. The C++ string class is god's gift to programmers, C strings have a set length and it takes some tweaking to change the length if you want to, but the C++ String class can dynamically change it's length with fair ease

    Array:
    char a[] = {'a','b','c','d'};

    C String:
    char a[] = {'a','b','c','d','\0'};
    or the short form which is the same
    char a[] = "abcd";

    C++ String:
    string a = "abcd";

    I can explain more with a better idea of what you don't understand.
