oracle
This is the oracle paper held on July 13 2003 at NITK Surathkal.
The test has 2 sections : 30 technical and 30 aptitude and 60
min time.
Technical section:
its very easy any one can answer 25 qns without preperation.
some are
1. how compiler treats variables of recursive functions
2. what is orthogonal matrix?
3. given two tables and asked 2 qns on those table ,
one is on join and another is on NOT IN
4. given some qns on pointers( pretty easy)
5. given five qns on data structures like , lifo, fifo
6. qtn on primary key
7. how NULL in sql is treated?
8. given a doubly linked list and asked r->left->right->data
ans: r->data
9:explain const char *ptr and char *const ptr
remaining i didn`t remember
aptiude
15 quant apti from rs agrval
15 verbal apti,
in this 4 are odd word out
and 4 are sentese ordering when jumbled senteses given
and 4 are reasoning
