Answer P22

value = 32
*pv   = 32
**ppv = 32

#include  <stdio.h> 

void main ( void )
{
  int value;
  int *pv;
  int **ppv;

  value = 32;
  pv = &value;
  ppv = &pv;

  printf("value = %d\n", value );
  printf("*pv   = %d\n", *pv );
  printf("**ppv = %d\n", **ppv ); /* slight change */
  
  system("pause");
}

Review: The following

  **ppv

is more common than its equivalent,

  *( *ppv )

but means the same thing.
