Multidimensional arrays are merely an abstraction for programmers, as all of the elements in the array are sequential in memory. Declaring int arr[2][4]; is the same thing as declaring int arr[8];. 2 Strings String literals such as “Hello, world!” are actually represented by C++ as a sequence of characters in memory.

Since C arrays (and C strings are essentially arrays) don’t automatically keep track of their dimensions or usage, it seems completely reasonable to capture all of that information inside of a struct , and use that to represent a flexible string type.

C-Strings So far we’ve mainly been looking at arrays of numbers. Arrays of characters have some special functions all their own. Arrays of characters are called strings, or more specifically, C-Strings (named after their use in the C programming language). C-Strings are not to be confused with the string data type that we have used previously.
