    You do not need to alply the ampersand sign (&) to read into an array. Since an array is a form of a pointer the & sign is not needed.

    Hmm..I was wrong. Funny how I have never come across that before but then again I never do use scanf() .

    The code doesn't even compile
    Code:
    Borland C++ 5.5 for Win32 Copyright (c) 1993, 2000 Borland
    junk1.c:
    Error E2451 junk1.c 5: Undefined symbol 'n' in function main
    Warning W8065 junk1.c 5: Call to function 'scanf' with no prototype in function main
    Warning W8065 junk1.c 8: Call to function 'printf' with no prototype in function main
    Warning W8070 junk1.c 16: Function should return a value in function main
    *** 1 errors in Compile ***
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
