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);

32. The User Work Area (UWA) is a set of Program variables declared in the host program to communicate the contents of individual records between
(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.

For each record type in the database schema, a corresponding program variable with the same format should be declared in the host program.

21. Which API is used to draw a circle ?
(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

(A) A = 0, B = 0, C = 1
(B) A = 0, B = C = 1
(C) A = 1, B = C = 0
(D) A = B = 1, C = 1
Flip-flop UGC Net Computer Science Paper II Dec 12

Answer A
Explanation : Nand gate behave opposite of and gate so if any 0 in input then result will be 1. So output Y will be 1 if A = 0, B = 0, C = 1

Nested Structure

Nested Structure C Language

As you know though structure we can process data record by record that is why structure is called user defined data type. In some specific case you nested structure where a structure is inside of a structure. For example when process a student record with their dob. Take a look on following example.
#include<stdio.h>
#include<conio.h>
#include<string.h>
typedef struct s
{
    int roll;
    char name[10];
    struct d
    {
         int dd,mm,yy;
    }dob;
}student;

Static Variable

Static Variable

A static variable initialize by 0 instead of garbage at the time of declaration. Static variable retain its value in memory till the program is running.

On the other hand auto variable lost its data when function scope pass out . But static variable retain its value whenever  scope get over.

You can trace that how many times a function is being called.

void test()
{
    static int k; /* k will retain its value when function scope goes down */
    printf("\nThis function being called %d times ",++k);
}

ROM is read only Non-Volatile memory written data into it while manufacturing. Data of Rom never get change in its entire life.

Example : BIOS,Firware,Console

PROM

PROM is Non-Volatime memory manufactured blank, a user writes program into it. Ones data written in PROM it never get change. PROM is permanent it retain its data when power goes off. you need a special device called a PROM programmer or PROM burner for writing data. The process of programming a PROM is sometimes called burning the PROM.

Example : mobile phones, Radio Frequency Identification cards (RFIDs), High Definition Media Interfaces (HDMI), and video game controllers
