(A) Declaring a set of numbers
(B) Sorting a list of strings
(C) Assigning a legal values possible for a variable
(D) Sequencing a list of operators
Answer C
Explanation : Enumeration is a special datatype which provide an integer number sequence to its member which help to track some common properties with meaning full name instead of number like color names

42. Which of the following mode declaration is used in C++ to open a file for input ?
(A) ios : : app
(B) in : : ios
(C) ios : : file
(D) ios : : in
Answer D
Explanation : ios::in allows input (read operations) from a stream.ios::out allows output (write operations) to a stream.

43. Data Encryption Techniques are particularly used for ______.
(A) protecting data in Data Communication System.
(B) reduce Storage Space Requirement.
(C) enhances Data Integrity.
(D) decreases Data Integrity.
Answer A
Explanation : when we send our data through public network then eavesdropping risk become high So we need some technique which increase security when data is send through public network.

Data encryption translates data into another form, or code, so that only people with access to a secret key (formally called a decryption key) or password can read it. Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext. Currently, encryption is one of the most popular and effective data security methods used by organizations. Two main types of data encryption exist - asymmetric encryption, also known as public-key encryption, and symmet

44. Let L be a set accepted by a non deterministic finite automaton. The number of states in non-deterministic finite automaton is |Q|. The maximum number of states in equivalent finite automaton that accepts L is
(A) |Q|
(B) 2|Q|
(C) 2|Q| – 1
(D) 2|Q|
Answer D
Explanation :In NFA there may be possibility to more than one state transition but in DFA state transition is single direction so about this question if NFA is |Q| then DFA may have 2|Q| state over this type of NFA.

49. Identify the operation which is commutative but not associative ?

(A) OR

(B) NOR

(C) EX-OR

(D) NAND

Answer D

Explanation :

1)Every logic gate follows Commutative law.

2)AND,OR,Ex-OR,EX-NOR follows Associative law. NAND,NOR doesn`t follow Associative law.

3)AND ,OR follows Distributive law.Ex-OR,EX-NOR,NAND,NOR doesn`t follow Distributive law.AND operation only distributive on EX-OR operation no other operation is distributive including itself.

31. Basis path testing falls under
(A) system testing
(B) white box testing
(C) black box testing
(D) unit testing
Answer : B
Explanation : The basis path testing is same, but it is based on a white box testing method, that defines test cases based on the flows or logical path that can be taken through the program. Basis path testing involves execution of all possible blocks in a program and achieves maximum path coverage with least number of test cases. It is a hybrid of branch testing and path testing methods.

The objective behind basis path testing is that it defines the number of independent paths, thus the number of test cases needed can be defined explicitly (maximizes the coverage of each test case).

     

     int a,b;

     for(a=1,b=2;a<=10;a++)

          printf("\n%d",a*b);

(A) DBMS & the Host record
(B) Host program and Host record
(C) Host program and DBMS
(D) Host program and Host language
Answer : C
Explanation :A set of program variables, declared in the host program, to communicate the contents of individual records between the DBMS and the host program.

(A) Circle ( )
(B) Ellipse ( )
(C) Round Rect ( )
(D) Pie ( )
Answer B
Explanation : In mathematics, an ellipse is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. As such, it is a generalization of a circle.
22. In DML, RECONNCT command
cannot be used with
(A) OPTIONAL Set
(B) FIXED Set
(C) MANDATOR Set
(D) All of the above
Answer B
Explanation : The RECONNECT command can be used with both OPTIONAL and MANDATORY sets, but not with FIXED sets. The RECONNECT command moves a member record from one set instance to another set instance of the same set type. It cannot be used with FIXED sets because a member record cannot be moved from one set instance to another under the FIXED constraint.

11. In compiler design ‘reducing the strength’ refers to
(A) reducing the range of values of input variables.
(B) code optimization using cheaper machine instructions.
(C) reducing efficiency of program.
(D) None of the above
Answer : B
Explanation :I

n compiler design , strength reduction is a compiler optimization where expensive operations are replaced with equivalent but less expensive operations. The classic example of strength reduction converts "strong" multiplications inside a loop into "weaker" additions – something that frequently occurs in array addressing.

Most of a program's execution time is typically spent in a small section of code (called a hot spot), and that code is often inside a loop that is executed over and over.

A compiler uses methods to identify loops and recognize the characteristics of register values within those loops.

12. In which addressing mode, the effective address of the operand is generated by adding a constant value to the contents of register ?
(A) Absolute
(B) Indirect
(C) Immediate
(D) Index
Answer : D
