Where feasible, automated or static allocation will likely be easiest because the storage is managed from the compiler, freeing the programmer of the potentially error-vulnerable chore of manually allocating and releasing storage. Having said that, lots of details buildings can transform check my site in dimensions at runtime, and since static allocations (and automatic allocations in advance of C99) will need to have a fixed sizing at compile-time, there are plenty of predicaments during which dynamic allocation is important.

In essence each individual const winds up on the right on the thing it constifies, including the const that is required
