Asked: May 14, 20262026-05-14T01:41:28+00:00 2026-05-14T01:41:28+00:00

void* ptr1 = NULL; void* ptr2 = ptr1; unsigned int *buf = data;//some buffer

  • 0
void* ptr1 = NULL;
void* ptr2 = ptr1;
unsigned int *buf = data;//some buffer

//now
ptr2 = buf + 8;

The above change in address of ptr2 is not reflected in ptr1.
I am trying void* ptr2 = &ptr1; too.

Please let me know whats the mistake here.

    If you want ptr1 to follow ptr2:

    void* ptr2 = NULL;
    void** ptr1 = (void **)&ptr2;
    unsigned int *buf = data;//some buffer
    
    //now
    ptr2 = buf + 8;
    

    Now *ptr1 follows ptr2
