  scanf("%s", yyy);  // input an string, begin to store at element yyy[0] until '\n' encountered 
  while( (xx = getchar()) != "EOF" ) // assign char input to xx 
                                     // evaluate if xx does not contains an end of file char
                                     // if ture, do what is inside the loop, 
                                     // and reevaluate the while expression
  printf("Some characters like %%,\n, -10.2%f, 27.3); // prints: 
Some characters like %,
