Malloc free is harder because thereâ s also calloc and realloc from question Does it matter for the free() and delete[] if allocation was done on stack or heap? |

No need to initialise to null before malloc but any variable pointers that you later free should be set to null and only free if not null;also initialise pointer values in your structs to null easier to use calloc and get this automatically so your guards work properly from question Freeing memory in a function |
