Answer P29

**ppi = 77
**ppi = 99

In this program, ppi constantly points to pv, but pv first points at one variable and then points at another.

#include  <stdio.h> 

void main ( void )
{
  int value = 77, num = 99 ;
  int *pv ;
  int **ppi ;

  ppi = &pv;
  
  pv  = &value;
  printf("**ppi = %d\n", **ppi );

  pv  = &num;
  printf("**ppi = %d\n", **ppi );

  system("pause");
}
