    Need some clearing out on this - (Arrays)

    Just been reading this http://www.cprogramming.com/tutorial/lesson9.html

    And im a little confused about this...

    To declare a string of 49 letters, you would want to say:

    char string[50];

    This would declare a string with a length of 50 characters. Do not forget that arrays begin at zero, not 1 for the index number.
    Wouldnt it be char String[49]; ?

    When you declare an integer array of 3 you dont say int array[4]; as the indexs would be...

    index[0],[1],[2],[3]

    Rather you would say int array[3]; with the indexs being index[0],[1],[2]

    Maybe this is diffrent in C++ or even strings for that matter...

    Can some one tell me im a idiot and why im one...

    Yep, so called c-style strings are null terminated character arrays. In order for them to behave like strings, they must end in a '\0' character. A good thing might be to forget you ever read about c-style strings and concentrate on C++ strings, which are of type string and they are declared in the header file <string>. They are much easier to use and provide more functionality than c-style strings.
