malloc vs free represents a topic that has garnered significant attention and interest. When and why to use malloc - Stack Overflow. 56 You use malloc when you need to allocate objects that must exist beyond the lifetime of execution of the current block (where a copy-on-return would be expensive as well), or if you need to allocate memory greater than the size of that stack (i.e., a 3 MB local stack array is a bad idea). c - Difference between malloc and calloc?
