Answer to Question nullterm-3

// numNonblanks(s) returns the number of nonblank
// characters in null-terminated string s.

int numNonblanks(const char* s)
{
  int count = 0;
  for(int i = 0; s[i] != '\0'; i++)
  {
    if(s[i] != ' ')
    {
      count++;
    }
  }
  return count;
}

// removeBlanks(s) returns a string (allocated using new)
// that holds all of the non-blank characters in s.

char* removeBlanks(const char* s)
{
  int   n = numNonblanks(s);
  char* t = new char[n + 1];
  int   j = 0;

  for(int i = 0; s[i] != '\0'; i++)
  {
    if(s[i] != ' ')
    {
      t[j] = s[i];
      j++;
    }
  }
  t[j] = '\0';
  return t;
}
