Chapter 11 - map_int() vs map_dbl()

[jimrothstein]

Chapter 11.1 Introduction

nitpicking: Text uses map_int but code uses map_dbl

Last sentence of first paragraph:

NOW: "You might create a function like this because it gives you a window to see how functionals, like map_int(), work."

HOWEVER: CODE: uses map_dbl() [because map_int() does not work in this example ]

SUGGEST: replace text with map_dbl
