C is more difficult than other language. Because it has pointer, you have to
think all the over flow conditions.
you can keep c to write basic algriothm.
Then you need to know a modern language. you'd better learn about JAVA than
C++.
And learn JAVA basic concept including class, inheritence, polymophsim,
encapsulation. And other terms.
I think you just use one month to study hard. You will be expert on JAVA are
. Just in basic java. Not on any other framework.
Then you need to prepare interivew question and write all the questions's
anwer.
At last, congratulation! you can take part in all the company's entry level'
s interview. You will find interivew so easy.
