    fatal error LNK1120

    I can not figure out the error codes from this program.

    #include <stdio.h>
    #define NUMS 7 /* establishes NUMCOLS as 5 */

    int main()
    { /* start of main */
    void display(int channels [NUMS]); /* function prototype */

    int channels[NUMS] = {2,4,5,7,9,11,13};/* declares array channels to have 7 numbers which are initialized to 2,4,5,7,9,11,13 */

    display(&channels [NUMS]);

    return 0;
    }

    void display(int * channels [NUMS])
    {
    extern int i;
    printf("\n%d %d %d %d %d %d %d", &channels);
    }


    I receive this message after building:

    1>------ Build started: Project: WA 4 B 1 Christopher Caron, Configuration: Debug Win32 ------

    Any help would be awesome.

    Re: fatal error LNK1120

    You have this:
    Code:
    void display(int channels [NUMS]); /* function prototype */
    and:
    Code:
    void display(int * channels [NUMS])
    See the difference?
