WebJun 9, 2024 · Static memory allocation can only be done on stack whereas dynamic memory allocation can be done on both stack and heap. An example of dynamic allocation to be done on the stack is recursion where the functions are put into call stack in order of their occurrence and popped off one by one on reaching the base case. WebThe memory_order enum specifies what types of reorderings compiler must forbid. relaxed - no constraints. consume - no loads that are dependent on the newly loaded value can be reordered wrt. the atomic load. I.e. if they are after the atomic load in the source code, they will happen after the atomic load too.
