8.7 Example 8.24, which considered the layout of a two-dimensional array of characters, counted only the space devoted to characters and pointers. This is appropriate if the space is allocated statically, as a global array of days or keywords known at compile time. Supposed instead that space is allocated in the heap, with 4 or 8 bytes of overhead for each contiguous block of storage. How does this change the tradeoffs in space efficiency? Example 8.24 char days [] [10] { char *days[] { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday" "Friday", "Saturday" "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday" "Friday", "Saturday" J; days [2] [3] 's'; /* in Tuesday */ days [2] [3] 's'; /* in Tuesday */ = =- Sa tur day
