Is freeing the allocated memory is really required every time, for a
program like this as freeing doesn’t bring in any change w.r.t memory
space (or) will it become a memleak some where down the line if it is
not freeed?
To avoid memory leaks, for each and every time you call malloc(), you
must call free() exactly once with the same pointer that was returned.
The only exceptions to this are:
1) if the call to malloc() returned NULL
2) if you are about to immediately terminate the program anyway*
