Whats is dynamic memory?

Dynamic memory - is that memory that are allocated to heap instead of stack. Heap - means that you can free or delete memory at any moement you want(DON'T FORGET TO DO THIS IF YOU ARE DOING NOT WITH SMART POINTER, or else you get memory leak that will consume Ram). Stack - means that you can't free or delete memory at any moment, memory will be automaticly deleted at the end of program.

Pros and Cons of using dynamic and static memory

Dynamic memory:

• Resizable size (size of array can grow if not enough size)
• Can control lifetime of variable or array

• Can lead to memory leaks if you not deleted allocated memory

Static memory:

• Auto deletion at the end of program (some say that is disadvantage but i think it is safer)
• Don't need to worry about memory leaks because it is stack

• Size of array is not rezisable it is hardcoded (if you try adding anything bigger then size of variable or array, will be error)
