this is because when you use malloc function it holds the space in heap but in case of assigning “Hello” string to a pointer, first the string is stored in Read only section of stack and then the address of this stack location is assigned to ptr.
thats why you’ll get segmentation fault in free(ptr) statement.
Also by doing this u’ll not able to free that memory ever in you program.
