The brain is leaking

Question

What are simple rules to have efficient memory in your code?

Answer 1

Sleep in times!
(But I still don't have any memory with code -_-)

Answer 2

• Use stack memory where possible. Allocating memory on the heap is very slow in comparison.

• Set your pointers to nullptr (or 0, in C) after freeing dynamic memory so you don't wind up with a dangling pointer. (This isn't necessary, but good practice if the pointer isn't immediately popped off of the stack.)

• Use the RAII principle to make it easier to make sure that all dynamic memory is freed.
