Problem Statement
Show how to explicitly allocate and deallocate blocks of memory in your language. Show access to different types of memory (i.e., heap, stack, shared, foreign) if applicable.
Let's start with the solution:
Step by Step solution about How to resolve the algorithm Memory allocation step by step in the Nim programming language
Source code in the nim programming language
# Allocate thread local heap memory
var a = alloc(1000)
dealloc(a)
# Allocate memory block on shared heap
var b = allocShared(1000)
deallocShared(b)
# Allocate and Dellocate a single int on the thread local heap
var p = create(int, sizeof(int)) # allocate memory
# create zeroes memory; createU does not.
echo p[] # 0
p[] = 123 # assign a value
echo p[] # 123
discard resize(p, 0) # deallocate it
# p is now invalid. Let's set it to nil
p = nil # set pointer to nil
echo isNil(p) # true
