Why use dynamically allocated memory

#1

i had seen that almost each time either creating a node for a data structure or making a helper array to solve a particular problem we use dynamic memory allovcation, what is the reason for it and what are the various advantages of doing so

Hey @Parmeet-Kalsi-1631789033630118
There are two memory spaces available to you :stack & heap
Stack has limited size and u have to start with predefined max space. All the arrays and variables u create in your code are allocated in heap unless u create them dynamically.
But while dynamically allocating nodes that memory is allocated on heap and can be decided on runtime.
So some advantages of Dynamic allocation are:

  • Data structures can grow and shrink according to the requirement.
    • We can allocate (create) additional storage whenever we need them.
    • We can de-allocate (free/delete) dynamic space whenever we are
      done with them.
  • Dynamic Allocation is done at run time.

I hope this resolves ur query :slight_smile:
