Pointers

• retrieve the address of a variable:
  pointerName = &variableName ;

  int* pi;
  pi = &i;

• retrieve the value stored at an address:
  variableName = *pointerName ;

  int j;
  j = *i;

• using pointers as arrays:
  

  const int bufferSize = 10;
  char buffer[bufferSize] = "J. Smith";
  char* bufPtr = buffer;
  while(*bufPtr != ' ') {
  bufPtr++;
  }
  std::cout « ++bufPtr « std::endl;
