Resize a Statically Allocated Array

i get 20 in both outputs, y has the array not grown ?

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main( void )
{
    int bytes[5];
    int * pBytes = bytes;

    printf("%d",sizeof(bytes));

    pBytes = (int*)realloc( pBytes, 2 * sizeof( bytes ) ); // grow it 2x

    printf("%d",sizeof(bytes));
   
    getchar();
    return 0;
}

---

What you did is allocate memory for pBytes. I don't know if this is ever guaranteed to work, as you used realloc() and pBytes had no memory allocated for it. I don't think you can change the size of a statically-allocated variable.

> pBytes = (int*)realloc( pBytes
You can't resize an array.
The only thing you can pass to realloc is the result of a previous malloc / calloc / realloc call.

thanx!

so statically allocated arrays cannot be resized!
