Join Dan Gookin for an in-depth discussion in this video Working with pointer arrays, part of Learning C (2014).
- A pointer is a variable.…A variable that holds a memory location.…As a variable it's possible, although terrifying…to some, to place pointers into an array.…Why and how you would want to do such a thing…is this movies topic.…Here I'll show you how to set up an array of pointers.…To keep things simple, I'll use strings for the example.…You'll see how to access strings,…evaluate the strings, and convert them from…array notation into pointer notation.…
A pointer array is simply a collection of memory addresses.…So, how do you get to the situation where you…need an array of addresses?…One of the best examples is to use an array of strings.…Here you see a pointer array.…It contains room for five memory locations.…Those locations are preset to the strings listed…in effect the declaration is for an array of strings,…although, that's not technically correct.…
The strings are displayed by using a four-loop…at line 14 built and run this code…and each string is displayed.…To prove that the array is a clutch of memory locations,…
