WA for MUL by spoj judge

my solution to MUL runs as expected on ide one.
However it fails with very large numbers.
The link to my code on ideone is

Yes. Your code fails for really large numbers. The input constraints say that the numbers can have up to 10000 digits.

How do I fix this???

Well, that is your task. Some / several SPOJ problems have been designed in a way that prohibits the naive use of standard data types. Sometimes you can work around this issue with clever algorithms or by switching to languages with built-in features (e.g. unlimited integer size in python) or libraries like BigInt in JAVA...
