Posted By : admin


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 ,
4.

One is on join and another is on NOT IN
5.

Given some qns on pointers( pretty easy)
6.

Given five qns on data structures like , lifo, fifo
7.

Qtn on primary key
8.

How NULL in sql is treated?
9.

Given a doubly linked list and asked r->left->right->data ans: r->data
10.

Explain const char *ptr and char *const ptr
11.

Remaining i didn`t remember

Consider the following C program and chose collect answer
#include
void main( )
{
inta[10],k;

D. 0
16.

Consider the prog and select answer
#include
void main ( )
{
int k=4,j=0:
switch (k)

C. 500
D. 0
17.

Consider the following statements:
Statement 1 A union is an object consisting of a sequence of named members of various types

B. except 4 all are correct
C. statemnt 3 is only correct

18.

consider the following program listing and select the output
