    Realloc help

    Ok I'm on the last page of my book and theres one small little problem I have been stuck on for about 20 minutes. I typed the code exactly how it says and in part of the code it does this:

    Code:
    int *arr;
    
    arr = calloc(5, sizeof(int));
    
    
    /* some code here...... etc... */
    
    
    /* then it gets to this */
    
    arr = realloc(8, sizeof(int));
    That last line is causing a compiler error that states:
    Warning: passing arg 1 of 'realloc' makes pointer from integer without a cast
    Yes, my program includes the proper <stdlib.h> library. No, I did not change the arr pointer type since the beginning. I don't quite understand how to fix this and what it is saying. Assistance would be appreciated. Thanks.

    >> arr = realloc(8, sizeof(int));

    It that's what's in your book, it's a misprint.

    realloc()

    Thanks. I see the book had an 8 where the pointer name that is being edited is supposed to go. Fixed.
