Malloc:
1. Takes only 1 argument- the size of the memory block to
be allocated.
2. Allocates memory as a single contiguous block.
3. Will fail if a single contiguous memory block of
required size is not available.
Calloc:
1. Takes two arguments - the number of memory blocks needed
and the size of each memory block.
2. It may or may not allocate a single contiguous block,
thus will not fail if a single contiguous memory block
of required size is not available.
3. Initialises the memory blocks to 0.

Given only putchar (no sprintf, itoa, etc.) write a routine putlong that prints out an unsigned long in decimal. [ I gave the obvious solution of taking % 10 and / 10, which gives us the decimal value in reverse order. This requires an array since we need to print it out in the correct order. The interviewer wasn't too pleased and asked me to give a solution which didn't need the array ].
