Re: CDAC Final Exam Papers

The details of the previous year question paper for the examination which is held by CDAC is as follows:

1. What is data structure?

Answer: A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other. Advance knowledge about the relationship between data items allows designing of efficient algorithms for the manipulation of data.

2. List out the areas in which data structures are applied extensively?

Compiler Design,
Operating System,
Database Management System,
Statistical analysis package,
Numerical Analysis,
Graphics,
Artificial Intelligence,
Simulation

3. What are the major data structures used in the following areas : RDBMS, Network data model & Hierarchical data model.

RDBMS ?? Array (i.e. Array of structures)
Network data model ?? Graph
Hierarchical data model ?? Trees

4. If you are using C language to implement the heterogeneous linked list, what pointer type will you use?

The heterogeneous linked list contains different data types in its nodes and we need a link, pointer to connect them. It is not possible to use ordinary pointers for this. So we go for void pointer. Void pointer is capable of storing pointer to any type as it is a generic pointer type.

5. Minimum number of queues needed to implement the priority queue? Two. One queue is used for actual storing of data and another for storing priorities.

6. What is the data structures used to perform recursion?

Stack. Because of its LIFO (Last In First Out) property it remembers its ??caller?? so knows whom to return when the function has to return. Recursion makes use of system stack for storing the return addresses of the function calls.
Every recursive function has its equivalent iterative (non-recursive) function. Even when such equivalent iterative procedures are written, explicit stack is to be used.

7. _________ is a point at which the debugger stops during program execution and awaits a further command.
Memory Dump
Watch point<------ans
Break point
None of these options

8. ________do not contain any program logic and are ignored by the language processor.

12. The Real constants in C can be expressed in which of the following forms
Fractional form only
Exponential form only
ASCII form only
Both Fractional and Exponential forms<------ans

13. The program, which translates high-level program into its equivalent machine language program, is called
Transformer
Language processor
Converter
None of these options<------ans

14. Consider the following statements.
i.Multiplication associates left to right
ii.Division associates left to right
iii.Unary Minus associates right to left
iv.subtraction associates left to right All are true <------ans
Only i and ii are true
All are false
Only iii and iv are true

15. What will be the value of variable a in the following code?
unsigned char a;
a = 0xFF + 1;
printf("%d", a);
0xFF
0x100
0 <------ans
