Thread: 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()

gg

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