Thanks for the suggestion.

Kindly bear with me for the following question.

I am just learning C at present. So I may not need SIZE_MAX memory
for testing purpose now.
However, in real world applications ie in Job envorinment(I am
preparing for interview/skill test, etc), will they have more than
4GB of RAM in order to test such code ?

I doubt it very much. Most code shops have pretty run-of-the-mill
collections of PCs, with as little RAM as they think they can get
away with.

I do not understand this. Kindly explain. Does it mean that in real
world applications SIZE_MAX memory won't be asked from malloc/realloc

No, it doesn't mean that.

or there won't be 4GB of input file for testing ?

No, it doesn't mean that, either. It just means that most companies are
unlikely to have a machine containing that much physical RAM.

malloc/realloc have size_t as parameter type which is unsgined int.
So, doesn't it mean that there may be requirement for 4GB of dynamic
memory ?

size_t may or may not be an unsigned int, and size_t may or may not be
32 bits wide. In your case, it seems, it is - but how do you know how
wide size_t will be on your interviewer's system?

There are always limits to any human endeavour, and that certainly
includes computing. Dealing intelligently with limits is a large part
of the skill involved in programming.
