Dynamic Memory Allocation
Why do we need dynamic memory allocation? - When the size of the array is passed as argument to the program
IMPORTANT !!! After you finished using the variable which you dynamically allocated, FREE the memory: void free(void *); Usage: free(vec); If you don’t - you will experience Memory Leak - no free memory !
Dangling Pointer - a pointer that points to a memory that is unreserved. (Example: allocate pointer and then reference to another location).
