Problem Statement
Dynamically allocated objects take their memory from a heap. The memory for an object is provided by an allocator which maintains the storage pool used for the heap. Often a call to allocator is denoted as where T is the type of an allocated object, and P is a reference to the object. The storage pool chosen by the allocator can be determined by either:
In the former case objects can be allocated only in one storage pool. In the latter case objects of the type can be allocated in any storage pool or on the stack.
The task is to show how allocators and user-defined storage pools are supported by the language. In particular:
Explain what controls the storage pool choice in the language.
Let's start with the solution:
Step by Step solution about How to resolve the algorithm Arena storage pool step by step in the PARI/GP programming language
Source code in the pari/gp programming language
pari_init(1<<20, 0); // Initialize PARI with a stack size of 1 MB.
GEN four = addii(gen_2, gen_2); // On the stack
GEN persist = gclone(four); // On the heap
